-------------------------------

             Summary: I can't read/write a Hbase table by spark-hbase connector when the table is  in non-default namespace
                 Key: HBASE-26491

             Project: HBase
          Issue Type: Bug
          Components: hbase-connectors
    Affects Versions: 1.0.0

I found I can't read/write a Hbase table by spark-hbase connector when the hbase table is  in a non-default namespace.

 

Because when spark opens a table(related to a hbase table), it creates a HBaseRelation instance first, and initializes a HBaseTableCatalog from the table definition saved in spark catalog. But in the function 'convert' the field 'tableCatalog' is constructed from a string template, in which the namespace is set as 'default', leading to a wrong namespace. This namespace is not  the one defined when user created the table before.

 

Pls have a look:
