Jonathan Ellis commented on CASSANDRA-4378:
-------------------------------------------
What would we do if we did catch the exception? Ignore it and corrupt data?
The only sane solution here is to fix the bug in the solr indexing code.
> MalformedInputException running cleanup on solr KS 'Logging', we should catch
> the exception

> Project: Cassandra

> The following occurred on 10 node cluster which we were running rebalance.
> Nick said it appeared to be related to running cleanup on a solr secondary
> index cf, and with this cluster it occurs when running cleanup on the Logging
> KS. Please note that we did run the solr_logging demo on this data prior to
> cleanup.
> The exception java.nio.charset.MalformedInputException: Input length = 1 is
> caused by incompatible data format.
> It comes from doCleanupCompaction method of CompactionManager.java from C*
> try
> { cfs.indexManager.deleteFromIndexes(row.getKey(), indexedColumnsInRow); }
> finally
> { Table.switchLock.readLock().unlock(); }
> it looks like something wrong with the key data in row.getKey()
