Accumulo卡住而不是开始

我一直在尝试安装Accumulo并试用几天，但在开始之前就已经存货了。我最终使用了安装了Hadoop和Zookeeper的HortonWorks Sandbox。 我按照Accmulo设置页面上的说明进行操作，并按如下方式更改配置：

[root@sandbox ~]# vi /etc/accumulo/conf/accumulo-env.sh
if [ -z "$ACCUMULO_HOME" ]
then
test -z "$ACCUMULO_HOME"     && export ACCUMULO_HOME=/usr/hdp/2.2.0.0-2041/accumulo
fi

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

# hadoop-1.2:
# test -z "$HADOOP_CONF_DIR"       && export HADOOP_CONF_DIR="$HADOOP_PREFIX/conf"
# hadoop-2.0:
test -z "$HADOOP_CONF_DIR"     && export HADOOP_CONF_DIR="$HADOOP_PREFIX/etc/hadoop/conf"

test -z "$JAVA_HOME"             && export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk.x86_64
test -z "$ZOOKEEPER_HOME"        && export ZOOKEEPER_HOME=/usr/hdp/current/zookeeper-client
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

使用此配置，我能够成功启动Accumulo：

[root@sandbox ~]# /usr/hdp/2.2.0.0-2041/accumulo/bin/start-all.sh

我还能够成功初始化Accumulo：

Warning!!! Your instance secret is still set to the default, this is not secure. We highly recommend you change it.
    You can change the instance secret in accumulo by using:

    You will also need to edit your secret in your configuration file by adding the property instance.secret to your conf/accumulo-site.xml. Without this accumulo will not operate correctly

然而，当我尝试启动一个Accumulo shell来尝试它时，它会被卡住而不会抛出任何错误：

[root@sandbox ~]# /usr/bin/accumulo shell --password reza

它没有进一步的进展不给我一个shell尝试。关于如何解决这个或问题是什么的任何建议？

2 个答案:

答案 0 :(得分：0)

您可能必须指定实例名称和ZooKeeper主机信息。使用--help启动shell以查找正确的命令行选项。

注意：您可以通过在命令行上使用--debug启动它来调试Accumulo shell。

答案 1 :(得分：0)

在尝试启动shell之前，您是否启动了Accumulo？

/usr/hdp/2.2.0.0-2041/accumulo/bin/start-all.sh

然后

/usr/bin/accumulo shell --password reza
