Kay Ousterhout commented on SPARK-19803:
----------------------------------------
This does not appear to be fixed -- it looks like there's some error condition
in the underlying code that can cause this to break? From
https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/74412/testReport/org.apache.spark.storage/BlockManagerProactiveReplicationSuite/proactive_block_replication___5_replicas___4_block_manager_deletions/:
org.scalatest.exceptions.TestFailedDueToTimeoutException: The code passed to
eventually never returned normally. Attempted 493 times over 5.007521253999999
seconds. Last failure message: 4 did not equal 5.

[~shubhamc] and [~cloud_fan], since you worked on the original code for this,
can you take a look at this? I looked at this for a bit and based on some
experimentation it looked like there were some race conditions in the
underlying code.
