---------------------------------------------
Summary: Non-existing commitlog dir emits warnings in tools/bin
Key: CASSANDRA-19779
URL: https://issues.apache.org/jira/browse/CASSANDRA-19779
Project: Cassandra
Issue Type: Bug
Components: Legacy/Tools
Reporter: Stefan Miklosovic
Assignee: Stefan Miklosovic
When I extract the distribution tarball and I want to use tools in tools/bin,
there is this warn log visible every time for tools when they are started (does
not happen on "help" command, obviously)
{code:java}
WARN 14:25:11,835 Unable to determine block size for commit log directory:
null {code}
This is because we introduced this (1) in CASSANDRA-18464
What that does is that it will go and try to create a temporary file in commit
log directory to get "block size" for a "file store" that file is in.
The problem with that is that when we just extract a tarball and run the tools
- Cassandra was never started - then such commit log directory does not exist
yet, so it tries to create a temporary file in a non-existing directory, which
fails, hence the log message.
The fix is to check if commitlog dir exists and return / skip the resolution of
block size if it does not.
