> Separate the old WALs into different regionserver directories

> Key: HBASE-14247
> URL: https://issues.apache.org/jira/browse/HBASE-14247
> Project: HBase
> Issue Type: Improvement
> Components: wal
> Reporter: Liu Shaohui
> Assignee: Liu Shaohui
> Priority: Minor
> Fix For: 2.0.0

>
> Currently all old WALs of regionservers are achieved into the single
> directory of oldWALs. In big clusters, because of long TTL of WAL or disabled
> replications, the number of files under oldWALs may reach the
> max-directory-items limit of HDFS, which will make the hbase cluster crashed.
> {quote}
> Caused by:
> org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.protocol.FSLimitException$MaxDirectoryItemsExceededException):
> The directory item limit of /hbase/lgprc-xiaomi/.oldlogs is exceeded:
> limit=1048576 items=1048576
> {quote}
> A simple solution is to separate the old WALs into different directories
> according to the server name of the WAL.
> Suggestions are welcomed~ Thanks
