What this means is that the programs written in Java can do several things (seemingly) at once. For example - even on machines with just one https://plumbr.eu/outofmemoryerror/unable-to-create-new-native-thread processor - while you drag content from one window to another, the movie played in the background does not stop just because you carry out several operations at once. A way to think about threads is to think of them as workers to whom you can submit tasks to carry out. If you had only one worker, he or she could only carry out one task at the time. But when you have a dozen workers at your disposal they can simultaneously fulfill several of your commands. Now, as with workers in physical world, threads within the JVM need some elbow room to carry out the work they are summoned to deal with. When there are more threads than there is room in memory we have built a foundation for a problem: The message java.lang.OutOfMemoryError: Unable to create new native thread means that the Java application has hit the limit of how many Threads it can launch. What is causing it?You have a chance to face the java.lang.OutOfMemoryError: Unable to create new native thread whenever the JVM asks for a new thread from the OS. Whenever the underlying OS cannot allocate a new native thread, this OutOfMemoryError will be thrown. The exact limit for native threads is very platform-dependent thus we recommend to find o
HDFS DataNode logs or those of any system daemonIf your nproc limit is incorrectly configured, the smoke tests fail and you see an error https://ambari.apache.org/1.2.0/installing-hadoop-using-ambari/content/ambari-chap5-3-1.html similar to this in the DataNode logs: INFO org.apache.hadoop.hdfs.DFSClient: Exception increateBlockOutputStream https://issues.apache.org/jira/browse/HADOOP-8396 java.io.EOFException INFO org.apache.hadoop.hdfs.DFSClient: Abandoning block blk_-6935524980745310745_139190 3.3.1. Solution:In certain recent Linux distributions (like RHEL v6.x/CentOS v6.x), the default value of nproc is lower than the value required if you are deploying the HBase service. To change this value:Using a text editor, open /etc/security/limits.d/90-nproc.conf and change unable to the nproc limit to approximately 32000. For more information, see ulimit and nproc recommendations for HBase servers.Restart the HBase server.ContentsSearch1. Getting Ready to Install1. Understand the Basics2.
