-------------------------------------
Summary: TServer should ensure wal settings are valid for
underlying FS
Key: ACCUMULO-2266
URL: https://issues.apache.org/jira/browse/ACCUMULO-2266
Project: Accumulo
Issue Type: Bug
Components: tserver
Affects Versions: 1.5.0
Reporter: Sean Busbey
Priority: Critical
Fix For: 1.5.1, 1.6.0
ACCUMULO-2264 revealed a problem in how the tserver handles conflicts between
it's settings and the restrictions of the underlying fs.
In the case of ACCUMULO-2264, if the tserver is configured with a wal block
size less than that allowed by HDFS the tserver sits in an infinite loop.
The tserver should probably be checking for the minimum blocksize (the property
is dfs.namenode.fs-limits.min-block-size) and then either issuing a WARN/ERROR
to the client and using the minimum or failing loudly and refusing to start. I
favor the latter.
