ResourceManager webapp code runs OOM
Prashant Kommireddi 2013-10-21, 22:53
Hello,

We are noticing the RM running out of memory in the webapp code. It happens
in
org.apache.hadoop.yarn.server.resourcemanager.webapp.AppsBlock.renderBlock(Block
html).

The StringBuilder object "appsTableData" grows too large in this case while
appending AppInfo. Ignoring the heap size (this should be fixed if I
increased the heapsize for sometime), is there a way to configure the
number of AppInfos that should be loaded? Or pagination?

Thanks,
Prashant
