RE: Managing space in Master Node
Hi Arko. Sounds like you may be running a DataNode on the NameNode which is
not recommended practice. Normally, the only files the NN stores are the
image and edits files. It does not store any actual HDFS data. If you must
run a DN on the NN, try turning down the logging in /conf/log4j.properties:


Depending on the logging information you require, of course.

Subject: Managing space in Master Node

Hello Gurus,

I am managing a Hadoop Cluster to run some experiments.

The issue I am continuously facing is that the Master Node runs out of disk
space due to logs and data files.

I can monitor and delete log files. However, I cannot delete the HDFS data.

Thus, is there a way to force Hadoop not to save any HDFS data in the Master

Then I can use my master to handle the metadata only and store the logs.

Thanks & regards
