TestDataNodeHotSwapVolumes fails occasionally with the following error. Ran it
~10 times locally and it passed every time.
{code}
Error Message
Failed to replace a bad datanode on the existing pipeline due to no more good
datanodes being available to try. (Nodes:
current=[DatanodeInfoWithStorage[127.0.0.1:46950,DS-e653e0ec-e490-47d3-9cca-cdd6dff3964a,DISK],
DatanodeInfoWithStorage[127.0.0.1:34486,DS-fd83f642-be1a-44ed-8ba5-6ad5a42e85fd,DISK]],
original=[DatanodeInfoWithStorage[127.0.0.1:34486,DS-fd83f642-be1a-44ed-8ba5-6ad5a42e85fd,DISK],
DatanodeInfoWithStorage[127.0.0.1:46950,DS-e653e0ec-e490-47d3-9cca-cdd6dff3964a,DISK]]).
The current failed datanode replacement policy is DEFAULT, and a client may
configure this via 'dfs.client.block.write.replace-datanode-on-failure.policy'
in its configuration.
