    Description

      As observed in a pre-commit test run:

      2020-11-25T14:05:33.605-08:00 WARN CBAS.nc.Task [org.apache.hyracks.api.rewriter.runtime.SuperActivity:JID:0.900:TAID:TID:ANID:ODID:0:0:3:0:0] Task failed with exception
      		 
      org.apache.hyracks.api.exceptions.HyracksDataException: HYR0104: Index does not exist
      		 
      	at org.apache.hyracks.api.exceptions.HyracksDataException.create(HyracksDataException.java:60) ~[hyracks-api.jar:7.0.0-1234]
      		 
      	at org.apache.hyracks.storage.am.common.dataflow.IndexDataflowHelper.readIndex(IndexDataflowHelper.java:77) ~[hyracks-storage-am-common.jar:7.0.0-1234]
      		 
      	at org.apache.hyracks.storage.am.common.dataflow.IndexDataflowHelper.destroy(IndexDataflowHelper.java:99) ~[hyracks-storage-am-common.jar:7.0.0-1234]

      eventually results in a halt, due to a missing primary index file on a shadow dataset that had just been created, but ingestion was interrupted during bootstrap.

      we create dataset testBucket.testScope.testCollection on testBucket.testScope.testCollection and immediately following that, we do alter collection testBucket.testScope.testCollection disable analytics
      because we are getting stopped before we connect, we don't have any index files
      drop dataset barfs because testBucket.testScope.testCollection's primary index doesn't exist yet
      It seems like IndexDataflowHelper.destroy should catch ErrorCode.INDEX_DOES_NOT_EXIST perhaps log and simply return, not propagate the exception
