Harsh J resolved HBASE-15235. ----------------------------- Resolution: Duplicate Dupe of HBASE-15236 > Inconsistent cell reads over multiple bulk-loaded HFiles > -------------------------------------------------------- > > Key: HBASE-15235 > URL: https://issues.apache.org/jira/browse/HBASE-15235 > Project: HBase > Issue Type: Bug > Reporter: Appy > Assignee: Appy > > If there are two bulkloaded hfiles in a region with same seqID and duplicate > keys*, get and scan may return different values for a key. > More details: > - one of the rows had 200k+ columns. say row is 'r', column family is 'cf' > and column qualifiers are 1 to 1000. > - hfiles were split somewhere along that row, but there were a range of > columns in both hfiles. For eg, something like - hfile1: ["", r:cf:70) and > hfile2: [r:cf:40, ....). > - Between columns 40 to 70, some (not all) columns were in both the files > with different values. Whereas other were only in one of the files. > In such a case, depending on file size (because we take it into account when > sorting hfiles internally), we may get different values for the same cell > (say "r", "cf:50") depending on what we call: get "r" "cf:50" or get "r" > "cf:". > I have been able to replicate this issue, will post the instructions shortly. > * not sure how this would happen. These files are small ~50M, nor could i > find any setting for max file size that could lead to splits. Need to > investigate more. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
