stack updated HBASE-6506: ------------------------- Attachment: 6506.txt Rerun. The javadoc and findbugs are not related. Nor the zombie. > Setting CACHE_BLOCKS to false in an hbase shell scan doesn't work > ----------------------------------------------------------------- > > Key: HBASE-6506 > URL: https://issues.apache.org/jira/browse/HBASE-6506 > Project: HBase > Issue Type: Bug > Components: shell > Affects Versions: 0.94.0 > Reporter: Josh Wymer > Priority: Minor > Labels: cache, ruby, scan, shell > Fix For: 0.99.0 > > Attachments: 6506.txt, 6506.txt > > Original Estimate: 1m > Remaining Estimate: 1m > > I was attempting to prevent blocks from being cached by setting CACHE_BLOCKS > => false in the hbase shell when doing a scan but I kept seeing tons of > evictions when I ran it. After inspecting "table.rb" I found this line: > cache = args["CACHE_BLOCKS"] || true > The problem then is that if CACHE_BLOCKS is false then this expression will > always return true. Therefore, it's impossible to turn off block caching. -- This message was sent by Atlassian JIRA (v6.2#6252)
