[jira] [Commented] (HBASE-14046) IllegalArgumentException: Negative
position from hfile.bucket.FileIOEngine.read
[ https://issues.apache.org/jira/browse/HBASE-14046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15147038#comment-15147038 ]
Anoop Sam John commented on HBASE-14046:
----------------------------------------
When this issue came, configured hbase.bucketcache.bucket.sizes to non default values? Seeing the code in converting long offset into an int baseOffset and one byte value, we have expectation on the bucket sizes. It has to multiple of 1024.. For other values seems we will get incorrect results.. Did not try to reproduce a -ve case.
