Bharath Mundlapudi commented on HDFS-2092: ------------------------------------------ Hi Aaron, That was just a sample of measurement for a day. We should care for MAX here in this case. Also, Going forward, PIG 0.9 will store lots of meta data in the conf and also one can embed the PIG script itself in the conf. This can potentially blow the TT. We can measure an approx size of conf by the job.xml file in the job history location. Since one can store anything in the job conf, we should be careful with the references to this object - we should not hold for long duration. > Create a light inner conf class in DFSClient > -------------------------------------------- > > Key: HDFS-2092 > URL: https://issues.apache.org/jira/browse/HDFS-2092 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs client > Affects Versions: 0.23.0 > Reporter: Bharath Mundlapudi > Assignee: Bharath Mundlapudi > Fix For: 0.23.0 > > Attachments: HDFS-2092-1.patch, HDFS-2092-2.patch > > > At present, DFSClient stores reference to configuration object.
