             Summary: temporary files need to be cleaned by unit tests
                 Key: CASSANDRA-7712
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7712
             Project: Cassandra
          Issue Type: Test
          Components: Tests
            Reporter: Michael Shuler
            Priority: Minor
             Fix For: 2.0.10, 2.1.1


There are many unit test temporary files left behind after test runs. In the 
case of CI servers, I have seen >70,000 files accumulate in /tmp over a period 
of time. Each unit test should make an effort to remove its temporary files 
when the test is completed.

My current unit test cleanup block:
{noformat}
# clean up after unit tests..
rm -rf  /tmp/140*-0 /tmp/CFWith* /tmp/Counter1* /tmp/DescriptorTest* 
/tmp/Keyspace1* \
        /tmp/KeyStreamingTransferTestSpace* /tmp/SSTableExportTest* 
/tmp/SSTableImportTest* \
        /tmp/Standard1* /tmp/Statistics.db* /tmp/StreamingTransferTest* 
/tmp/ValuesWithQuotes* \
        /tmp/cassandra* /tmp/jna-* /tmp/ks-cf-ib-1-* /tmp/lengthtest* 
/tmp/liblz4-java*.so /tmp/readtest* \
        /tmp/set_length_during_read_mode* /tmp/set_negative_length* 
/tmp/snappy-*.so
