Maryann Xue commented on PHOENIX-1929:
--------------------------------------
[~samarthjain], yes, it looks like the same problem, but PHOENIX-1562 was a
random failure and could not be reproduced, so I was not sure if my patch then
had really fixed the problem.
In theory, "cacheUsingTableRef" should never be null, nor should
"cacheUsingTableRef.getTable()". When adding cache, we use
cacheUsingTableRef.getTable() to find all HBase regions the table has. And
right before it returns with success, it adds this tableRef into the
cacheUsingTableRefMap. I think we need to find why this is null at the point of
close() instead of covering this problem.
