[SPARK-23275] hive/tests have been failing when run locally on the laptop
(Mac) with OOM
## What changes were proposed in this pull request?
hive tests have been failing when they are run locally (Mac Os) after a
recent change in the trunk. After running the tests for some time, the test
fails with OOM with Error: unable to create new native thread.
I noticed the thread count goes all the way up to 2000+ after which we
start getting these OOM errors. Most of the threads seem to be related to the
connection pool in hive metastore (BoneCP-xxxxx-xxxx ). This behaviour change
is happening after we made the following change to HiveClientImpl.reset()
``` SQL
def reset(): Unit = withHiveState {
try {
// code
} finally {
runSqlHive("USE default") ===> this is causing the issue
}
```
I am proposing to temporarily back-out part of a fix made to address
SPARK-23000 to resolve this issue while we work-out the exact reason for this
sudden increase in thread counts.
## How was this patch tested?
Ran hive/test multiple times in different machines.
