I ran WriteAheadLogIT by itself and it passed. It looks like my VM just ran
out of disk space.
During the BigRootTabletIT... the RFile is being closed by SSI during
switchSource. Here's my debug exception stacktrace:
```
at
org.apache.accumulo.core.file.rfile.RFile$LocalityGroupReader.close(RFile.java:714)
at
org.apache.accumulo.core.file.rfile.RFile$Reader.closeLocalityGroupReaders(RFile.java:1173)
at
org.apache.accumulo.core.file.rfile.RFile$Reader.close(RFile.java:1194)
at
org.apache.accumulo.core.iterators.system.SourceSwitchingIterator.switchSource(SourceSwitchingIterator.java:167)
```
This looks like the same issue in LargeRowIT.
@keith-turner I think this proves your concerns about closing RFiles that
are reused. Sadly, the SSI seemed like one of the system Iterators that could
benefit from this change.
