------------------------------------
Summary: Failure to cleanup WAL split dir log should be at INFO
level
Key: HBASE-27175
URL: https://issues.apache.org/jira/browse/HBASE-27175
Project: HBase
Issue Type: Task
Reporter: Viraj Jasani
Fix For: 2.5.0, 3.0.0-alpha-4, 2.4.14
As part of the SCP, after we are done splitting WALs, we try removing the
-splitting dirs but if the dir doesn't exist, dfs#delete fails with IOE. Since
we are aware of this case, we just log the message but we don't interrupt SCP
because handling of the failure is gracefully done.
Hence, failure to remove "-splitting" dir should not be mentioned as WARN log,
let's convert this to INFO level:
{code:java}
LOG.warn("Remove WAL directory for {} failed, ignore...{}", serverName,
e.getMessage()); {code}
Any other genuine failure to remove the splitting dir is anyways covered by
this log, hence we don't have worry about keeping the above mentioned log at
WARN level, we have anyways mentioned "ignore..." in the log message.
{code:java}
if (!fs.delete(splitDir, false)) {
LOG.warn("Failed delete {}, contains {}", splitDir, fs.listFiles(splitDir,
true));
} {code}
