Hi,
I try to write the data in hdfs using flume on windows machine. Here I
configure flume and hadoop on same machine and write data into hdfs its works
perfectly.
But configure hadoop and flume on different machines (both are windows
machines). I try to write data in hdfs it shows the following error.
