Since the task I was running was reduce heavy, I chose to just drop the number of mappers from 4 to 2.

You also have to remember that there is some overhead from the OS, the Java code cache, and a bit from running the JVM. http://outwardsound.com/cannot-allocate/cannot-allocate-memory-linux-error.html I'd recommend upgrading the JDK as a long-term stable solution. c) The whoami call has been removed. If you have either lots of swap space configured or have overcommit_memory=1overcommit_memory=1 then I don't think there's any performance penalty to using fork(). Cannot Allocate Memory Jvm

The problem is that for simple file system tasks like creating symbolic links or checking for available disk space, Hadoop forks a process from the TaskTracker.
The workaround here is to either use an instance with more memory (m2 class), or reduce the number of mappers or reducers you are running on each machine to free up Kill some of the jobs which are not required. The standard workaround seems to be to keep a subprocess around and re-use it, which has its own set of problems. There Is Insufficient Memory For The Java Runtime Environment To Continue. This trick has been used by squid (unlinkd) and many other applications quite effectively to offload all of the forking.
In the clone man page, "If CLONE_VM is not set, the child process runs in a separate copy of the memory space of the calling process at the time of clone. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage.

Handling date/time in Apache Pig A common usage scenario for Apache Pig is to analyze log files. http://hudson.gotdns.com/wiki/display/HUDSON/IOException+Not+enough+space When checking with strace, it was failing at [pid 7927] clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x4133c9f0) = -1 ENOMEM (Cannot allocate memory) Without CLONE_VM. I'm a Java newbie, so my question is, though it got solved, did I do something properly? Of course you can try other solutions mentioned here (like over-committing or upgrading to a JVM that has the fix).

Show Doug Cutting added a comment - 15/Jan/09 21:33 Based on: http://www.win.tue.nl/~aeb/linux/lk/lk-9.html It sounds like maybe the safer thing to do is to increase swap to equal RAM and set overcommit_memory=2. Most don't, and rightfully so, as it causes memory management from an operations perspective to be wildly unpredictable.
