Gautham Banasandra updated HDFS-15927:
--------------------------------------
Description:
Need to catch polymorphic exception types by reference in order to realize the
polymorphic usage, if any. Otherwise, the functionality of the caught object is
restricted to only that of the base class.
Also, the following warning gets reported since it's currently caught by value -
{code:java}
