[jira] [Commented] (STORM-964) Add config (with small default
value) for logwriter to restrict its memory usage

STORM-964, add config for worker logwriter to restrict its mem usage
The log writer process that writes out stderr and stdout should have a config that controls it's memory usage and it should default to a very small value, probably 50MB in most cases.
To address above issue, one new parameter is defined for logwriter's jvmopts: "topology.worker.lw.childopts".
The default heap size of logwriter is set as 64M, or user can override it through "-c topology.worker.lw.childopts='xxxx " when submitting a topology.
