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. ...
