问题描述
我正在尝试在 spark-shell 中使用 HBase。有两个集群：Cloudera 和 Hortonwork。 Cloudera 集群执行完美的命令，而 Hortonwork one 以相同的命令失败并出现奇怪的错误：
scala> new HBaseContext(sc,conf)
<console>:30: error: type mismatch;
found : org.apache.spark.org.apache.spark.org.apache.spark.org.apache.spark.org.apache.spark.SparkContext
required: org.apache.spark.org.apache.spark.org.apache.spark.org.apache.spark.org.apache.spark.SparkContext
Error occurred in an application involving default arguments.
new HBaseContext(sc,conf)
^
以下是 spark-shell 在 HDP 上的更详细输出：
scala> import org.apach.hadoop.hbase.HBaseConfiguration
import org.apach.hadoop.hbase.HBaseConfiguration
warning: Class org.apache.yetus.audience.InterfaceAudience not found - continuing with a stub
scala> import org.apache.hadoop.hbase.spark.HBaseContext
org.apache.hadoop.hbase.spark.HBaseContext
warning: Class org.apache.yetus.audience.InterfaceAudience not found - continuing with a stub
error: missing or invalid dependency detected while loading class file 'HBaseContext.class'.
Could not access term yetus in package org.apache,because it (or its dependencies) are missing. Check your build deFinition for
missing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic classpath.)
A full rebuild may help if 'HBaseContext.class' was compiled against an incompatible version of org.apache.
