--------------------------------------
Summary: YARN HBase token code shouldn't swallow invocation target
exceptions
Key: SPARK-11317
URL: https://issues.apache.org/jira/browse/SPARK-11317
Project: Spark
Issue Type: Bug
Reporter: Steve Loughran
As with SPARK-11265; the HBase token retrieval code of SPARK-6918
1. swallows exceptions it should be rethrowing as serious problems (e.g
NoSuchMethodException)
1. Swallows any exception raised by the HBase client, without even logging the
details (it logs that an `InvocationTargetException` was caught, but not the
contents)
As such it is potentially brittle to changes in the HDFS client code, and
absolutely not going to provide any assistance if HBase won't actually issue
tokens to the caller.
The code in SPARK-11265 can be re-used to provide consistent and better
exception processing
