Ted Yu commented on HBASE-19551: -------------------------------- lgtm Is it possible to verify this fix in cluster ? > hbck -boundaries doesn't work correctly > --------------------------------------- > > Key: HBASE-19551 > URL: https://issues.apache.org/jira/browse/HBASE-19551 > Project: HBase > Issue Type: Bug > Components: hbck > Reporter: Toshihiro Suzuki > Assignee: Toshihiro Suzuki > Attachments: HBASE-19551.patch > > > Currently, in HBaseFsck#checkRegionBoundaries(), it seems like keys from > reader.getFirstKey() and reader.getLastKey() are directly compared by > ByteArrayComparator: > https://github.com/apache/hbase/blob/9d0c7c6dfbcba0907cbbc2244eac570fcc4d58a5/hbase-server/src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java#L864-L865 > https://github.com/apache/hbase/blob/9d0c7c6dfbcba0907cbbc2244eac570fcc4d58a5/hbase-server/src/main/java/org/apache/hadoop/hbase/util/HBaseFsck.java#L869-L870 > This is not correct because the keys consist of a key length and key itself. > We should compare rowkeys or the only key itself (by removing a key length). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
