java.lang.IllegalAccessError: class com.google.protobuf.HBaseZeroCopyByteString

hadoop mr 或者 spark 操作 hbase时候就出现这个错误

这是hbase的bug,可在jira上看到该问题:https://issues.apache.org/jira/browse/HBASE-10304

hadoop yarn 解决方案:

提交作业方式

$ export HADOOP_CLASSPATH="/home/cluster/apps/hbase/lib/hbase-protocol-0.98.1-cdh5.1.0.jar"
$ ./hadoop-2.2.0/bin/hadoop --config /home/stack/conf_hadoop/ jar ./hbase/hbase-assembly/target/hbase-0.99.0-SNAPSHOT-job.jar  org.apache.hadoop.hbase.mapreduce.RowCounter usertable

增加HADOOP_CLASSPATH到linux环境变量中

增加如下内容到bashrc 或者 bash_profile 或者 profile ,这样是linux环境变量中就行

export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/home/cluster/apps/hbase/lib/hbase-protocol-0.98.1-cdh5.1.0.jar

spark 解决方案:

提交作业方式

-conf 增加spark.driver.extraClassPath & spark.executor.extraClassPath

spark-submit --class com.umeng.dp.yuliang.play.HBaseToES --master yarn-cluster --conf "spark.driver.extraClassPath=/home/cluster/apps/hbase/lib/hbase-protocol-0.98.1-cdh5.1.0.jar" --conf "spark.executor.extraClassPath=/home/cluster/apps/hbase/lib/hbase-protocol-0.98.1-cdh5.1.0.jar"   --jars /home/cluster/apps/hbase/lib/hbase-protocol-0.98.1-cdh5.1.0.jar ScalaMR-0.0.1-jar-with-dependencies.jar

增加如下配置到$SPARK_HOME/conf/spark-defaults.conf文件

spark.driver.extraClassPath /home/cluster/apps/hbase/lib/hbase-protocol-0.98.1-cdh5.1.0.jar
spark.executor.extraClassPath /home/cluster/apps/hbase/lib/hbase-protocol-0.98.1-cdh5.1.0.jar
