Work Description: suztomo commented on issue #10222: [BEAM-8822] Hadoop
client version 2.8.5 from 2.7
URL: https://github.com/apache/beam/pull/10222#issuecomment-559190042
Got it. Thank you for clarification. I'll check how Beam's Hadoop
functionality is tested.
Memo: Still I feel I need to verify whether Hadoop-client 2.8 is compatible
with Hadoop cluster 2.7.
- If it's compatible, then we can think about creating integration tests for
multiple Hadoop versions (2.7 and 2.8).
- If Hadoop-client 2.8 is not compatible with Haodop cluster 2.7, then some
modules need to be split in the same manner as Flink's.

> About compatibility with other library:
> Hadoop client 2.7 is not compatible with Guava > 21 because of
> Objects.toStringHelper. Fortunately Hadoop client 2.8 removed the use of the

> 2.8.5 is the latest in 2.8.X.
