Hello, I am encountering strange error using HBase 0.90.3, the scenario:
I am writing KeyValues in Sequence files as an intermediate input for further bulk loading using MapReduce. The problem I am facing is that when I try to read the KeyValues from the sequence file in the Mapper (in order to emit them for sorting) they are garbled and thus the whole job fails because of the Exceptions thrown by trying to process the garbled keyvalues. For instance, when trying to output the KeyValue object I get java.lang.ArrayIndexOutOfBoundsException or java.lang.RuntimeException: Unknown code XX. I have spent a lot of time in order to track down the bug and found out that when I write the SequenceFile of KeyValues with HBase 0.90.3 I cannot read the content back using the same HBase version jar, however I am able to read it without any problems with HBase 0.20.* versions. It is easily reproducible with this unit test. As for Hadoop, I am using the Cloudera distribution CDH3 Beta 2. Thanks for help.
