Nandor Kollar commented on HADOOP-14459:
----------------------------------------
[~templedf] thanks for the comments! Attached patch HADOOP-14459_2.patch. It
seems that the original problem (HADOOP-8588) is no longer present with
getTrimmedStrings, looks like only getStrings caused NPE in this case. In the
second diff, a warning is emitted if the value is not defined, or is set to
null. If it is undefined, then SerializationFactory will use the defaults
passed to getTrimmedStrings, but for empty value nothing is added. Daniel, what
do you think?
> SerializationFactory shouldn't throw a NullPointerException if the
> serializations list is not defined
