Java heap space

kr_ratan — Fri, 16 Sep 2022 09:58:08 GMT

I have Configured HDFS & HIVE on Fedora 20 (32 bit linux) on VM. HDFS and HIVE is running properly on VM, but problem occurs when trying to connect through any external tool or program like jasper or java.

PFB the error for reference-

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at org.apache.thrift.protocol.TBinaryProtocol.readStringBody(TBinaryProtocol.java:353) at org.apache.thrift.protocol.TBinaryProtocol.readMessageBegin(TBinaryProtocol.java:215) at org.apache.thrift.TServiceClient.receiveBase(TServiceClient.java:69) at org.apache.hadoop.hive.service.ThriftHive$Client.recv_execute(ThriftHive.java:116) at org.apache.hadoop.hive.service.ThriftHive$Client.execute(ThriftHive.java:103) at org.apache.hadoop.hive.jdbc.HiveStatement.executeQuery(HiveStatement.java:192) at org.apache.hadoop.hive.jdbc.HiveStatement.execute(HiveStatement.java:132) at org.apache.hadoop.hive.jdbc.HiveConnection.configureConnection(HiveConnection.java:133) at org.apache.hadoop.hive.jdbc.HiveConnection.<init>(HiveConnection.java:122) at org.apache.hadoop.hive.jdbc.HiveDriver.connect(HiveDriver.java:106) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at Hive_test.main(Hive_test.java:20)

Following JARS i have included-

ant-1.8.1.jar apache-httpcomponents-httpclient.jar apache-httpcomponents-httpcore.jar commons-el-1.0-javadoc.jar commons-el-1.0-sources.jar commons-el-1.0.jar commons-logging-1.1.1.jar commons-logging-api-1.0.4.jar connector-sdk-1.99.5.jar hadoop-common-2.6.0.2.2.4.2-2.jar hive-beeline-0.12.0.jar hive-cli-0.12.0.jar hive-common-0.12.0.jar hive-contrib-0.12.0.jar hive-exec-0.12.0.jar hive-exec-0.8.0.jar hive-exec-0.8.0.jar.zip hive-io-exp-core-0.6.jar.zip hive-io-exp-deps-0.6-sources.jar.zip hive-io-exp-deps-0.6.jar.zip hive-jdbc-0.12.0.jar hive-metastore-0.12.0.jar hive-service-0.12.0.jar httpclient-4.2.5.jar httpcore-4.2.4.jar jackson-core-asl-1.8.8.jar jasper-compiler-5.5.23.jar jasper-runtime-5.5.23.jar jsp-api-2.1-sources.jar jsp-api-2.1.jar junit-4.11-javadoc.jar junit-4.11-sources.jar junit-4.11.jar libfb303-0.9.0.jar libthrift-0.9.0.jar log4j-1.2.16-javadoc.jar log4j-1.2.16-sources.jar log4j-1.2.16.jar ql.jar slf4j-api-1.6.1-javadoc.jar slf4j-api-1.6.1-sources.jar slf4j-api-1.6.1.jar slf4j-log4j12-1.6.1.jar sqoop-connector-kite-1.99.5.jar

So please suggest any corrective action.

System is running out of memory

Hive is trying to create tez container and system does not have enough Memory

Check the vm memory and see if you can increase it

Could you post some of you heap configurations? How much memory is available on the machine? OOM error usually means the heap configuration is not correct or their is not enough memory available on the machine.

You also might want to check the open files limit (ulimit -a), if its too low it can cause OOM errors. (see https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.2/bk_installing_manually_book/content/ref-729d1fb0-6d1b-459f-a18a-b5eba4540ab5.1.html)

Even though you might be able to run Hadoop on a 32bit system, I wouldn't recommend it. You should use a 64bit system (see http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.2/bk_installing_manually_book/content/meet-min-system-requirements.html)
