[jira] [Resolved] (HBASE-9925) Don't close a file if doesn't EOF
while replicating
[ https://issues.apache.org/jira/browse/HBASE-9925?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Esteban Gutierrez resolved HBASE-9925.
--------------------------------------
Resolution: Later
Resolving for later, we should better fix other replication bottlenecks before we hit some contention from the NN.

> Key: HBASE-9925
> URL: https://issues.apache.org/jira/browse/HBASE-9925
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.98.0, 0.96.0
> Reporter: Himanshu Vashishtha
>
> While doing replication, we open and close the WAL file _every_ time we read entries to send. We could open/close the reader only when we hit EOF. That would alleviate some NN load, especially on a write heavy cluster.
> This came while discussing our current open/close heuristic in replication with [~jdcryans].
