Subject Data doesn't write in HDFS
Date Fri, 27 Mar 2015 04:48:52 GMT
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.
