> 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}
