如何增加 Accumulo 代理服务器上的内存？

Question

Currently running a big data job that is doing lots of small inserts into an accumulo table, however after running for about an hour will always get an OOM exception

Is there a way to increase the memory when you start off the proxy server either through the command line or the config file? their documentation is spare and doesnt off much insight.

./bin/accumulo proxy -p proxy/proxy.properties #option to increase memory

Answer 1

The bin/accumulo command you're executing is a bash shell script that sources conf/accumulo-env.sh where you'd normally set some Java command-line options.

The provided launch scripts are a bit confusing in versions prior to Accumulo 2.x, but is anticipated to be much simpler and more direct/intuitive in 2.0.0 and later. In 1.9.x (and maybe some earlier versions), you can add appropriate Java flags to increase memory to the ACCUMULO_OTHER_OPTS environment in the conf/accumulo-env.sh file.
