[jira] [Created] (HBASE-11576) ExportSnapshot should be able to work the other way

Jean-Marc Spaggiari created HBASE-11576:
-------------------------------------------

             Summary: ExportSnapshot should be able to work the other way
                 Key: HBASE-11576
                 URL: https://issues.apache.org/jira/browse/HBASE-11576
             Project: HBase
          Issue Type: Bug
            Reporter: Jean-Marc Spaggiari

ExportSnapshot should be able to run from the target cluster and export the snapshot from the source
cluster. That way we don't need to run the MapReduce framework on the source cluster.

[jira] [Resolved] (HBASE-11570) Command to list files part of a snapshot


     [

Jean-Marc Spaggiari resolved HBASE-11570.
-----------------------------------------

    Resolution: Won't Fix

By looking closer, not a good idea. Even if we provide a list, this list might not be valid anymore after few
milliseconds if another compaction occurs.

[jira] [Created] (HBASE-11575) Pseudo distributed mode does not work as documented

Enis Soztutar created HBASE-11575:
-------------------------------------

             Summary: Pseudo distributed mode does not work as documented 
                 Key: HBASE-11575
                 URL: https://issues.apache.org/jira/browse/HBASE-11575
             Project: HBase
          Issue Type: Bug
            Reporter: Enis Soztutar
            Priority: Critical
             Fix For: 0.99.0

After master-RS colocation, now the pseudo dist-mode does not work as documented since you cannot start a
region server in the same port 16020. 

I think we can either select a random port (and info port) for the master's region server, or document how to
do a pseudo-distributed setup in the book.

As mentioned elsewhere, we can leverage hbase-10070 features to create replicas for the meta tables
regions so that: 
 1. meta hotspotting can be circumvented 
 2. meta becomes highly available for reading

[jira] [Created] (HBASE-11573) Report age on eviction

             Summary: Report age on eviction
                 Key: HBASE-11573
                 URL: https://issues.apache.org/jira/browse/HBASE-11573

            Reporter: stack
            Assignee: stack

From the parent issue, Todd reminds us of the old Jim Gray '5 minute rule' on whether to cache.

In master, we were reporting age only it was the inactionable inverse of 'how long blocks are staying in the cache'.

Let me add to our cache stats a histogram of age on eviction and change the UI reporting so it is age at eviction
(plus stddev).  The JSON version has percentiles (and if wanted, the old age report of age of items in cache).

[jira] [Created] (HBASE-11572) Add support for doing get/scans against a particular replica_id

Enis Soztutar created HBASE-11572:
-------------------------------------

             Summary: Add support for doing get/scans against a particular replica_id
                 Key: HBASE-11572
                 URL: https://issues.apache.org/jira/browse/HBASE-11572
             Project: HBase
          Issue Type: Sub-task
            Reporter: Enis Soztutar

We have support for doing an rpc against the primary region in get/scans and also new functionality for
doing failover get/scan RPCs trying primary first then doing backup rpcs to secondaries when the first
one times out. 

We can add functionality for doing get/scan against a particular replica_id so that we can use it in tests,
or by clients in some specific situations. 

We can think about adding support for querying the replica_id from get/scan responses coming from
failover rpcs so that the client can then issue a follow up request against that particular replica_id.

[jira] [Created] (HBASE-11571) Bulk load handling from secondary region replicas

          Issue Type: Sub-task
            Reporter: Enis Soztutar

We should be replaying the bulk load events from the primary region replica in the secondary region replica
so that the bulk loaded files will be made visible in the secondaries. 

This will depend on HBASE-11567 and HBASE-11568

            Reporter: Jean-Marc Spaggiari

HBase provide an export snapshot command to MR copy the snapshot files into a remove cluster. However, if
current cluster is not running MR, but target cluster is, we will need to export the list of files into the
target cluster and run a distcp from there.

To do so, given a snapshot name we need HBase to provide the list of files belonging to it.

[jira] [Created] (HBASE-11569) Flush / Compaction handling from secondary region replicas

Enis Soztutar created HBASE-11569:

             Summary: Flush / Compaction handling from secondary region replicas

                 URL: https://issues.apache.org/jira/browse/HBASE-11569
             Project: HBase
          Issue Type: Sub-task
            Reporter: Enis Soztutar

We should be handling flushes and compactions from the primary region replica being replayed to the
secondary region replica via HBASE-11568. 

Some initial thoughts for how can this be done is discussed in HBASE-11183. More details will come together
with the patch.
