Shalin Shekhar Mangar updated SOLR-5739:
----------------------------------------
Attachment: SOLR-5739.patch
Patch uses createShard overseer command to create the shard removing the need
to pass shard state, range and parent to the core admin create command.
> SPLITSHARD creates shards "...Ignoring commit while not ACTIVE"

> Environment: Windows 7 64 bit, Debian 3.11.1
> Reporter: Günther Ruck
> Assignee: Shalin Shekhar Mangar

> I've tried to use the SPLITSHARD command from the Solr collection-Api.
> A JUnit test successfully runs before the split, but fails after splitting
> the shard, stopping and restarting Solr. It won't fail if Solr isn't
> restarted after splitting.
> I found some entries in files "solr.log" and "core.properties" which may give
> hints.
> h6. After split:
> {{org.apache.solr.update.UpdateLog; Starting to buffer updates.
> FSUpdateLog{state=ACTIVE, tlog=null}}
> is logged for both newly created shards in "solr.log"
> "clusterstate.json" from Solr Cloud admin page shows:
> {{shard1 state: inactive (replica: active)}}
> {{shard1_0 state: active parent shard1 (replica active)}}
> {{shard1_1 state: active parent shard1 (replica active)}}
> Both "core.properties" files of the newly created shards have
> {{shardState=construction and shardParent=shard1}}
> entries.
> The "core.properties" file of the parent shard is not changed.
> h6. When restarting Solr
> and running the JUnit again these entries are logged:
> {{org.apache.solr.update.processor.DistributedUpdateProcessor; Ignoring
> commit while not ACTIVE - state: BUFFERING replay:0}}
> in "solr.log"
> I mainly I followed the steps of this tutorial
> http://architects.dzone.com/articles/solr-43-shard-splitting-quick.
> # (install solr-4.6.1)
> # create a small cluster:
> java -Dbootstrap_confdir=./solr/portalse/conf
> -Dcollection.configName=portalse -DzkRun -DnumShards=1 -DmaxShardsPerNode=2
> -DreplicationFactor=1 -jar start.jar
> # Run the unit test (after termination only one document exists).
> # Split the only shard:
> curl
> 'http://localhost:8983/solr/admin/collections?action=SPLITSHARD&collection=portalse&shard=shard1'
> shard "collection1_shard1_0_replica1" created (1 document)
> shard "collection1_shard1_1_replica1" created (0 documents)
> # commit index:
> curl 'http://localhost:8983/solr/portalse/update' --data-binary '<commit/>'
> -H 'Content-type:application/xml'
> # stop Solr by pressing Ctl-C.
> # restart Solr:
> java -DzkRun -jar start.jar
> # Run the unit test from step 2 again.
