stack updated HBASE-2889: ------------------------- Fix Version/s: (was: 0.90.0) Moving out. Don't need to finish this 'feature' for 0.90. > Tool to look at HLogs -- parse and tail -f > ------------------------------------------ > > Key: HBASE-2889 > URL: https://issues.apache.org/jira/browse/HBASE-2889 > Project: HBase > Issue Type: Bug > Components: wal > Reporter: stack > Assignee: stack > Attachments: 2889.txt, HBASE-2889_2.patch > > > We need a tool for looking at wals. A tail -f would be sweet though it might > be ugly having to open each time it wants to dump next lot of edits out wal > log. > From Kannan: > {code}20:45 <kannan> WALEdit already has a toString(). > 20:46 <kannan> And append/sync support allows you to read concurrently a file > that is being written too... (like JDs replication). > 20:46 <kannan> So it would be good if I could do a bin/hbase hlogprint -f > hdfs://...../.logs/<filename> -v -p > 20:46 <kannan> much like the HFile pretty printer... except the HLog one is > effectively a tail -f. > {code} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
