@felixcheung Seems master build is broken because R tests are broken (https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test/job/spark-master-test-sbt-hadoop-2.7/2844/console). I am not sure if this PR caused that. Can you help to take a look?

[felixcheung]

No, don't think so. Is there a recent change to catalog APIs - the failed tests are with table names. ``` Failed ------------------------------------------------------------------------- 1. Failure: test tableNames and tables (@test_sparkSQL.R#682) ------------------ length(tableNames()) not equal to 1. 1/1 mismatches [1] 3 - 1 == 2 2. Failure: test tableNames and tables (@test_sparkSQL.R#683) ------------------ length(tableNames("default")) not equal to 1. 1/1 mismatches [1] 3 - 1 == 2 3.
