Ted Yu created HBASE-16455:
------------------------------
Summary: Provide API for obtaining highest file number among all
the WAL files
Key: HBASE-16455
URL: https://issues.apache.org/jira/browse/HBASE-16455
Project: HBase
Issue Type: Improvement
Reporter: Ted Yu
Assignee: Ted Yu
Currently RegionServerServices has the following API:
{code}
WAL getWAL(HRegionInfo regionInfo) throws IOException;
{code}
Caller can only obtain filenum for a specific WAL.
When multi wal is in use, we should add API for obtaining highest file number
among all the outstanding WAL files.
User can pass null to getWAL() method above, but the filenum for the returned
WAL may not be the highest among all the WAL files.
See log snippet in the first comment.
