回答1:
I have added the hbase-conf path in hadoop classpath and the issue has been resolved .
Thanks!
回答2:
Though a bit different context but I faced a similar type of exception while connecting hive with hbase. Guess what! My hbase table's column mapping was mis-configure. After I configured hbase tables's columns properly(Metadata of the table),the issue vanished.
WITH SERDEPROPERTIES("hbase.columns.mapping" = "personal data:,:key")
