[jira] [Created] (HBASE-3702) Exec throws a npe while writing a
method that has a null value argument
Exec throws a npe while writing a method that has a null value argument
-----------------------------------------------------------------------
Key: HBASE-3702
URL: https://issues.apache.org/jira/browse/HBASE-3702
Project: HBase
Issue Type: Bug
Components: coprocessors
Reporter: Himanshu Vashishtha
Exec write method invokes getClass() on its arguments list for finding the argument's class, which gives a npe in case the argument is null. There is already an parameterClasses array in Invoker (its super class), which is populated with correct values (by method.getParameterTypes()). One can use it this array.

Himanshu Vashishtha commented on HBASE-3702:
--------------------------------------------
A similar bug is there in ExecResult.write(DataOutput) when it is writing a null value, it throws a npe.
There should be a check that in case of null value one should use Writable else invoke .getClass().
