Konstantin Shvachko commented on HDFS-3462:
-------------------------------------------
+ int originalXcievers =
conf.getInt(DFSConfigKeys.DFS_DATANODE_MAX_RECEIVER_THREADS_KEY,0);
should use DFS_DATANODE_MAX_RECEIVER_THREADS_DEFAULT rather than 0.
> TestDFSClientRetries.busyTest() should restore default xceiver count in the
> config.

> TestDFSClientRetries.busyTest() sets maximum xceiver count in the config to a
> small value, but does not restore it back to the default. As the result
> subsequent tests can fail, especially on slower or busy machines.
