(Revision 1388695) Result = FAILURE jdcryans : Files : * /hbase/branches/0.94/src/main/java/org/apache/hadoop/hbase/replication/regionserver/ReplicationSink.java > Refactoring ReplicationSink to make it more responsive of cluster health > ------------------------------------------------------------------------ > > Key: HBASE-6550 > URL: https://issues.apache.org/jira/browse/HBASE-6550 > Project: HBase > Issue Type: New Feature > Components: Replication > Reporter: Himanshu Vashishtha > Assignee: Himanshu Vashishtha > Fix For: 0.94.2, 0.96.0 > > Attachments: 6550-havealook.txt, HBase-6550-0.94.patch, > HBase-6550-0.94-v2.patch, HBase-6550-0.94-v3.patch, HBase-6550.patch, > HBase-6550-v1.patch, HBase-6550-v3.patch, HBase-6550-v4.patch, > HBase-6550-v5.patch, HBase-6550-v6.patch > > > ReplicationSink replicates the WALEdits in the local cluster. It uses native > HBase client to insert the mutations. Sometime, it takes a while to process > it (may be due to region splitting, gc pause, etc) and it undergoes the > retrial phase. > It has two repercussions: > a) The regionserver handler which is serving the request (till now, a > priority handler) is blocked for this period. > b) The caller may get timed out and it will retry it anyway, but the handler > serving the ReplicationSink requests is still working. > Refactoring ReplicationSink to have the following features: > a) Making it more configurable (have its own number of retrial limit, > connection timeout, etc) > b) Add a fail fast behavior so that it bails out in case caller is timedout, > or any exception in processing the mutation batch. -- This message is automatically generated by JIRA.
