Hi Guys,

I am trying to perform one Map Reduce task, but it shows me the below error.

INFO org.apache.hadoop.HDFS.DFSClient: Exception in createBlockOutputStream java.net.SocketTimeoutException: 69000 millis timeout while waiting for channel to be ready for connect. ch : java.nio.channels.SocketChannel[connection-pending remote=/ xxx:50010]

How can I solve this error?

Hi@akhtar,

This type of error indicates a write issue. In this case, the master wants to split the log. It does not have a local DataNodes so it tries to connect to a remote DataNode, but the DataNode is dead. To avoid this error, try to ready one Datanode in running state and then try your task.
