Wei Zheng commented on HIVE-13730:
----------------------------------
Here's an todo item after HIVE-13755 is fixed.
Right now memory manager doesn't guarantee to allocate enough memory for each
table in n-way join case. After fixing that issue, this assert below can be put
into HybridHashTableContainer's cstr after the variables have been determined.
{code}
assert writeBufferSize * (numPartitions - numPartitionsSpilledOnCreation)
<= memoryThreshold :
"hive.auto.convert.join.noconditionaltask.size is set too low. It's not
enough to " +
"allocate " + (numPartitions - numPartitionsSpilledOnCreation) + "
partitions (each " +
" of size " + writeBufferSize;
{code}
