Manno15 opened a new issue #159:
URL: https://github.com/apache/accumulo-testing/issues/159
**Describe the bug**
RandomCachedLookupsPT alters some of the tserver configs. If the cluster
that is running the test lacks the memory it will throw the exception below but
will continuously hang until manually canceled. The main issue here is the
exception is hidden in the logs and isn't properly handled by the PT to check
for it.
```
java.lang.IllegalArgumentException: Maximum tablet server map
memory 265,751,101 block cache sizes 3,301,756,108 and mutation
queue size 40,265,318 is too large for this JVM configuration 805,306,368
```
**To Reproduce**
Steps to reproduce the behavior (or a link to an example repository that
reproduces the problem):
1. Use the default (smaller) performance profile for fluo-uno
2. Run the RandomCachedLookupsPT
3. It will appear that the test is hanging. Checking the tserver logs will
show the error above.
**Expected behavior**
Ideally, the PT should check beforehand to make sure that the system it is
testing on can handle the system config changes it makes or at least exit
nicely when an exception is thrown.
**Additional context**
This PT does pass as expected when using the larger performance profile for
fluo-uno.
