Question

从搜索中，我发现了这个问题，按照说明我遇到了同样的问题。

CDH4 Hbase using Pig ERROR 2998 java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/filter/Filter

但是对我没用。此外，我使用的是Ubuntu和Hadoop-2.2.0，Hbase-0.96.1-hadoop2和Pig-0.12.0。

的.bashrc

export JAVA_HOME=/usr
export HADOOP_INSTALL=/home/ubuntu/hadoop-2.2.0
export PATH=$PATH:$HADOOP_INSTALL/bin
export PATH=$PATH:$HADOOP_INSTALL/sbin
export HADOOP_MAPRED_HOME=$HADOOP_INSTALL
export HADOOP_COMMON_HOME=$HADOOP_INSTALL
export HADOOP_HDFS_HOME=$HADOOP_INSTALL
export YARN_HOME=$HADOOP_INSTALL

export HADOOP_COMMON_LIB_NATIVE_DIR=${HADOOP_COMMON_HOME}/lib/native
export HADOOP_OPTS="-Djava.library.path=${HADOOP_COMMON_HOME}/lib"
export PIG_HOME=/home/ubuntu/pig-0.12.0
export HBASE_HOME=/home/ubuntu/hbase-0.96.1-hadoop2
export PIG_CLASSPATH="'${HADOOP_INSTALL}/bin/hbase classpath':$PIG_HOME/bin"

我做对了

export PIG_CLASSPATH = $ PIG_HOME / pig-0.12.0-withouthadoop.jar：$ HBASE_HOME / hbase-0.94.1.jar：$ HBASE_HOME / lib / *：$ HADOOP_COMMON_LIB_NATIVE_DIR / lib / *：$ PIG_CLASSPATH

错误org.apache.pig.tools.grunt.Grunt - 错误2998：未处理的内部错误。组织/阿帕奇/的Hadoop / HBase的/过滤/ WritableByteArrayComparable
