Suresh Srinivas updated HADOOP-6460: ------------------------------------ Resolution: Fixed Release Note: The ipc server response buffers that have grown to a large size (more than 1MB) is replaced by a smaller buffer to free up java heap used. This addresses the issue of large growth in namenode java heap usage. Status: Resolved (was: Patch Available) > Namenode runs of out of memory due to memory leak in ipc Server > --------------------------------------------------------------- > > Key: HADOOP-6460 > URL: https://issues.apache.org/jira/browse/HADOOP-6460 > Project: Hadoop Common > Issue Type: Bug > Affects Versions: 0.20.1, 0.21.0, 0.22.0 > Reporter: Suresh Srinivas > Assignee: Suresh Srinivas > Priority: Blocker > Fix For: 0.20.2, 0.21.0, 0.22.0 > > Attachments: hadoop-6460.1.patch, hadoop-6460.5.patch, > hadoop-6460.6.patch, hadoop-6460.7.patch, hadoop-6460.patch, > hadoop-6460.rel20.patch > > > Namenode heap usage grows disproportional to the number objects supports > (files, directories and blocks).
