Murtadha Hubail commented on ASTERIXDB-1114:
--------------------------------------------
I already have a patch up in gerrit:
https://asterix-gerrit.ics.uci.edu/#/c/413/
The real issue could be easily tested and avoided by adding any of this to the
BaseOperationTracker constructor:
assert datasetInfo != null
or
if(datasetInfo == null){
throw new IllegalStateException("...")
But since the getDatasetInfo() now would never return null, there is no need to
add it.
What really need to be tested is things like checkpointing and shutting down
successfully.
