Subject [jira] [Commented] (HBASE-15314) Allow more than one backing file in bucketcache
Date Mon, 16 Jan 2017 07:37:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15823572#comment-15823572

chunhui shen commented on HBASE-15314:

bq. So this is similar to what the 1st patches in this jira doing

Yes, but the 1st patch doesn't handle the case which read/write data cross multiple files.
The function of FileIOEngine#accessFile could be copied to the patch from the attachment 'FileIOEngine.java'
