--------------------------------------

             Summary: Test failure in PMetaDataImplTest
                 Key: PHOENIX-2256
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2256
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.6
         Environment: Happens on both Ubuntu and Fedora, running 64-bit Java 8.
            Reporter: James Heather


f I make a fresh clone of the repo, and then run mvn package, I get a test failure:

{code}
    -------------------------------------------------------------------------------

    Test set: org.apache.phoenix.schema.PMetaDataImplTest

    -------------------------------------------------------------------------------

    Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.027 sec <<< FAILURE! - in org.apache.phoenix.schema.PMetaDataImplTest

    testEviction(org.apache.phoenix.schema.PMetaDataImplTest)  Time elapsed: 0.027 sec  <<< FAILURE!

    java.lang.AssertionError: expected:<3> but was:<2>

        at org.junit.Assert.failNotEquals(Assert.java:834)

        at org.junit.Assert.assertEquals(Assert.java:645)

        at org.junit.Assert.assertEquals(Assert.java:631)

        at org.apache.phoenix.schema.PMetaDataImplTest.testEviction(PMetaDataImplTest.java:98)
{code}

This appears to be a bug in {{PMetaDataImpl.java}}. The test looks right.

Table {{b}} should get evicted first, which creates enough space for {{d}}. But in fact {{c}} gets evicted first, and then {{b}} needs to be evicted as well to make enough room.

I don't know if there's a race condition in here somewhere. It's odd that no one has picked up on a failing test before, so I'm wondering whether it succeeds in some environments. But it fails for me on both Ubuntu and Fedora (both with 64-bit Java 8).
