Rohini Palaniswamy commented on PIG-4620:
-----------------------------------------
Case 2 error is expected as you need to specify hbase. Without that it is taken
as a path relative to fs.defaultFS working directory and paths can't have :
Case 1 error is most likely because you have hbase jars in the classpath which
do not have support for namespace yet. If you look at
http://svn.apache.org/viewvc/hbase/branches/0.98/hbase-common/src/main/java/org/apache/hadoop/hbase/TableName.java?revision=1573948&view=markup
isLegalFullyQualifiedTableName method, it does check for NAMESPACE_DELIM
which is : . So ensure you have hbase jars which support namespace in your pig
classpath. You can run the pig script with -secretDebugCmd or -printCmdDebug
(both are same) to get the classpath with which pig will be run.

> Key: PIG-4620
> URL: https://issues.apache.org/jira/browse/PIG-4620
> Project: Pig
> Issue Type: New Feature
> Affects Versions: 0.15.0
> Reporter: Andi Chirita
> Assignee: Andi Chirita
> Labels: hbase, patch
> Attachments: HBaseStorageNamespace.patch
>
>
> Since version 0.96 HBase introduced namespace support.
> Apace Pig has recently updated the HBase dependency to 0.98.12 (PIG-4544)
> Currently there's no way to specify the namespace for a table.
> I suggest to implement it is using a '-namespace' option.
> {code}
> copy = STORE raw INTO 'hbase://SampleTableCopy'
> USING org.apache.pig.backend.hadoop.hbase.HBaseStorage(
> 'info:first_name info:last_name friends:* info:*','-namespace
> SampleNamespace');
> {code}
> We can't use the namespace in the hbase path as it will break the uri
> validation : 'hbase://SampleNamespace:SampleTableCopy'
> The patch is available. I will look to extend the unittest for the namespace
> option.
> Please review my changes and let me know if I can help with something.
> Kind regard,
> Andi
