[jira] [Commented] (HBASE-14363) Print more details on the row
behind an Empty REGIONINFO_QUALIFIER warning
[ https://issues.apache.org/jira/browse/HBASE-14363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14954219#comment-14954219 ]

----------------------------------------
Hi [~qwertymaniac], The HBCK -details flag provides keys (but not values) for 'hbase:meta' row with empty REGIONINFO_QUALIFIER's.
For example here is HBCK -details output when the 'hbase:meta' table is missing a 'info:region info' column for a 't1' table with one region:
{noformat}
ERROR: Empty REGIONINFO_QUALIFIER found in hbase:meta
Number of empty REGIONINFO_QUALIFIER rows in hbase:meta: 1
keyvalues={t1,,1444650621481.3da6b22dcf0498f89fe3a3cb8b8afe39./info:seqnumDuringOpen/1444692021935/Put/vlen=8/seqid=0, t1,,1444650621481.3da6b22dcf0498f89fe3a3cb8b8afe39./info:server/1444692021935/Put/vlen=15/seqid=0, t1,,1444650621481.3da6b22dcf0498f89fe3a3cb8b8afe39./info:serverstartcode/1444692021935/Put/vlen=8/seqid=0, t1,,1444650621481.3da6b22dcf0498f89fe3a3cb8b8afe39./info:sn/1444692021907/Put/vlen=29/seqid=0, t1,,1444650621481.3da6b22dcf0498f89fe3a3cb8b8afe39./info:state/1444692021935/Put/vlen=4/seqid=0}

It doesn't have regionserver info (as that is a value) but is the currently displayed info enough to avoid manually scanning 'hbase:meta'? I can log more if needed.

> Currently HBCK just prints a vague "Empty REGIONINFO_QUALIFIER found" warning, and does not print the row it found that on. While fixing this is easy thanks to HBCK, some more detail (say the row/region ID) would be good to print, to avoid people manually scanning meta to obtain the very same info.
