-----------------------------------------
Summary: EOFException log spam in Datanode
Key: HDFS-13875
URL: https://issues.apache.org/jira/browse/HDFS-13875
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs
Affects Versions: 3.0.0
Reporter: Karthik Palanisamy
Assignee: Karthik Palanisamy
Ambari checks datanode liveness by simply connecting to data transfer port. But
this connection will be closed after a successful TCP handshake without any
data transfer. Due to which datanode encountered EOFExcetion when reading an
encrypted message from the closed socket.
This issue addressed in
[HDFS-9572|https://issues.apache.org/jira/browse/HDFS-9572]. But not handled
for encrypted data transfer(SASL message).
