Aleksey Yeschenko created CASSANDRA-5193:
--------------------------------------------
Summary: Memtable flushwriter can pick a blacklisted directory
Key: CASSANDRA-5193
URL: https://issues.apache.org/jira/browse/CASSANDRA-5193
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.2.1
Reporter: Aleksey Yeschenko
Assignee: Aleksey Yeschenko
Fix For: 1.2.2
The top-level data directory will be picked by DiskAwareRunnable (directory =
Directories.getLocationCapableOfSize(writeSize)), and the top-level data
directory itself might not be blacklisted (most likely won't be).
For the same reason we can't just add a blacklist-check in the middle of
Directories#getLocationCapableOfSize - most often it's the sstable directory
that gets blacklisted.
The issue seems to be caused by/related to CASSANDRA-4292, which was committed
just two days prior 2116-2118 and undid some blacklist-aware directory-picking
logic.
Anyway, DiskAwareRunnable should be altered to respect directory blacklist.
