I am using spark 1.3.0 with hbase 1.0. After one week. Hbase run successful with java code. But when using Hbase with spark giving error. I also check with hbase shell is work fine. This errors occurred after long time otherwise work fine with spark also.
I already check hadoop and hbase cluster health is fine.
