Subject Re: Query HBase : Scan : Fwd: [New comment] HBase shell commands
Date Mon, 31 Mar 2014 15:15:42 GMT
For #1, please take a look at the following method in HTable:

  public boolean checkAndPut(final byte [] row,

      final byte [] family, final byte [] qualifier, final byte [] value,

      final Put put)

For #2, can you clarify your goal ?

Java API provides stronger capability compared to shell commands.

Cheers
