> When calcite is not on the HMS classpath, and query based compaction is enabled then
the compaction fails with NoClassDefFound error. Since the catch block only catches Exceptions
the following code block is not executed:
> {code:java}
> } catch (Exception e) {
>   LOG.error("Caught exception while trying to compact " + ci +
>       ".  Marking failed to avoid repeated failures, " + StringUtils.stringifyException(e));
>   msc.markFailed(CompactionInfo.compactionInfoToStruct(ci));
>   msc.abortTxns(Collections.singletonList(compactorTxnId));
> }
> {code}
> So the compaction is not set to failed.
> Would be better to catch Throwable instead of Exception
