Accumulo init - [start.Main]錯誤：初始化類加載器

我是Accumulo的新手，嘗試在Cloudera VM上安裝v1.7。Accumulo init - [start.Main]錯誤：初始化類加載器

我有Java 1.7和HDP 2.2，Zookeeper目前正在運行。我主要是在試圖跟隨INSTALL.md無事，並已經配置但是Accumulo在嘗試初始化時出現以下錯誤：

我讀過這個地方已經放下一個壞設置其他職位然而accumulo-env.sh下面我看不出有什麼我在想念

if [[ -z $HADOOP_HOME ]] ; then 
    test -z "$HADOOP_PREFIX"  && export HADOOP_PREFIX=/usr/lib/hadoop 
else 
    HADOOP_PREFIX="$HADOOP_HOME" 
    unset HADOOP_HOME 
fi 

# hadoop-2.0: 
test -z "$HADOOP_CONF_DIR"  && export HADOOP_CONF_DIR="$HADOOP_PREFIX/etc/hadoop" 
test -z "$ACCUMULO_HOME"   && export ACCUMULO_HOME="/etc/accumulo/accumulo-1.7.0" 
test -z "$JAVA_HOME"    && export JAVA_HOME="/usr/java/jdk1.7.0_67-cloudera" 
test -z "$ZOOKEEPER_HOME"  && export ZOOKEEPER_HOME=/usr/lib/zookeeper 
test -z "$ACCUMULO_LOG_DIR"  && export ACCUMULO_LOG_DIR=$ACCUMULO_HOME/logs 
if [[ -f ${ACCUMULO_CONF_DIR}/accumulo.policy ]] 
then 
    POLICY="-Djava.security.manager -Djava.security.policy=${ACCUMULO_CONF_DIR}/accumulo.policy" 
fi

而且我已經在我的general.classpaths以下

<property> 
<name>general.classpaths</name>

任何幫助將不勝感激，有趣的是，我試圖運行時得到相同的結果./bin/accumulo classpath

Accumulo預計從您的Hadoop安裝拉commons-io-2.4.jar。我不確定CDH是否打包了這個jar，或者你的配置文件沒有正確指出它。

您可以嘗試檢查accumulo classpath的輸出以查看類路徑中的項目實際擴展到的內容。 accumulo-site.xml中的general.classpath配置項是您想要檢查/修改的項目。

謝謝elserj，我已經編輯了我的general.classpath以包含此內容（請參閱上文），但仍然遇到同樣的問題。根據我原來的帖子（最後一行），我無法檢查'accumulo classpath'的輸出，因爲得到相同的錯誤 – jhole89

糟糕，抱歉。我錯過了關於無法運行classpath cmd的最後一點:)。你可以嘗試'find -L/usr/lib/hadoop -name'commons-io-2.4.jar''，並將其與general.classpaths中的正則表達式進行比較。 – elserj

取消設置CLASSPATH

我有同樣的問題，我花了時間來弄明白。
