UI parallelism options don't match Cassandra

[corey-cole]

The UI stores the string description value of the parallelism option when creating a repair, but when Reaper tries to retrieve the repair from the database, it fails with the following stack trace:

ERROR [2016-12-14 20:13:30,824] [dw-22 - GET /repair_run] i.d.j.e.LoggingExceptionMapper - Error handling a request: 18b1eccefcda9f42 java.lang.IllegalArgumentException: No enum constant org.apache.cassandra.repair.RepairParallelism.parallel at java.lang.Enum.valueOf(Enum.java:238) ~[na:1.8.0_102] at org.apache.cassandra.repair.RepairParallelism.valueOf(RepairParallelism.java:26) ~[cassandra-reaper-0.3.2-SNAPSHOT.jar:0.3.2-SNAPSHOT] at com.spotify.reaper.storage.postgresql.RepairRunMapper.map(RepairRunMapper.java:41) (deleted the rest)

I can (temporarily) get the repair in the database to appear in the UI by changing the value in repair_run.repair_parallelism to the enumeration name (e.g. PARALLEL instead of parallel).

This is reaper 0.3.2 against Cassandra 2.25 using Postgres as a storage backend.

Hi @corey-cole,

branch fix-issue-32 should fix the issue by using fromName() instead of valueOf() to match the value to the enum constant when using postgres as storage backend.

Let us know if that fixes your issue, so that we can merge the fix into master.

Thanks

That did the trick. Thanks for the quick fix.
