ql/src/java/org/apache/hadoop/hive/ql/metadata/HiveMetaStoreChecker.java (line 385) <https://reviews.apache.org/r/48520/#comment202258> My bad for the not catching this earlier. Realized this could be dangerous as it is inside a recursive call. For each level of the directory, you are creating a new thread pool, which means that you can potentially go all the way to create (#THREADS)^(#levels) worker threads instead of (#THREADS) and effectively choke the system. You need to share the thread pool amongst all the recursive calls, so that way you dont create a new pool for each level of recursion. - Hari Sankar Sivarama Subramaniyan On June 10, 2016, 11:58 p.m., pengcheng xiong wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
