Hudson commented on HBASE-10966: -------------------------------- SUCCESS: Integrated in HBase-TRUNK #5085 (See [https://builds.apache.org/job/HBase-TRUNK/5085/]) HBASE-10966 RowCounter misinterprets column names that have colons in their qualifier (stack: rev 1587443) * /hbase/trunk/hbase-server/src/main/java/org/apache/hadoop/hbase/mapreduce/RowCounter.java * /hbase/trunk/hbase-server/src/test/java/org/apache/hadoop/hbase/mapreduce/TestRowCounter.java > RowCounter misinterprets column names that have colons in their qualifier > ------------------------------------------------------------------------- > > Key: HBASE-10966 > URL: https://issues.apache.org/jira/browse/HBASE-10966 > Project: HBase > Issue Type: Bug > Affects Versions: 0.99.0 > Reporter: Alexandre Normand > Assignee: Alexandre Normand > Priority: Trivial > Fix For: 0.99.0, 0.94.19, 0.98.2, 0.96.3 > > Attachments: 10966v094.txt, HBASE-10966-1.patch > > > RowCounter allows for column names to be specify at command line: > {code} > Usage: RowCounter [options] <tablename> [--range=[startKey],[endKey]] > [<column1> <column2>...] > For performance consider the following options: > -Dhbase.client.scanner.caching=100 > -Dmapred.map.tasks.speculative.execution=false > {code} > However, the column names are parsed assuming that if there is a colon, there > are only two parts to the string. In other words, it assumes > {{family:qualifier}} where {{qualifier}} wouldn't contain a colon. > This came up as I was trying to do a row count on a {{kiji}} table where > qualifiers typically have multiple colon-delimited components (i.e. {{B:C}} > could be a qualifier in the {{B}} family). > The flaw is in this code: > {code} > String [] fields = columnName.split(":"); > if(fields.length == 1) { > scan.addFamily(Bytes.toBytes(fields[0])); > } else { > byte[] qualifier = Bytes.toBytes(fields[1]); > qualifiers.add(qualifier); > scan.addColumn(Bytes.toBytes(fields[0]), qualifier); > {code} -- This message was sent by Atlassian JIRA (v6.2#6252)
