Installation Accumulo被绊倒，无法启动

我已经尝试安装Accumulo并试用了几天，但它甚至在开始之前就被储存起来了。我最终使用了Hadoop和Zookeeper附带的HortonWorks沙盒。 我按照Accmulo设置页面上的说明进行操作，并将配置更改如下：

[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：

但是，当我尝试启动Accumulo shell进行尝试时，它会被卡住而不会抛出任何错误：

它没有任何进展，也没有给我一个壳去尝试。有没有关于如何解决此问题或问题所在的建议？

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Accumulo外壳程序来调试它。

在尝试启动外壳程序之前是否启动了Accumulo

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

然后

/usr/bin/accumulo shell --password reza

---

您是在初始化后立即尝试连接，还是重新启动/挂起沙箱然后重试？我过去在暂停/挂起虚拟机时遇到过问题。奇怪的是，你能够初始化，因为这意味着它已经启动了。你能进入监控界面吗？您可能还希望确保ZK已启动并正在运行。不熟悉沙箱，但在我的系统上，您可以像这样连接到zk:

zookeeper客户端-服务器zk01 ls/accumulo

我尝试连接到zookeeper，但一切正常。事实上，Accumulo可以在“全部启动”期间连接到它。我还尝试在初始化后立即连接。有人找到解决方案吗？例如：

accumulo shell-u root-zh zoo1:2181、zoo2:2181、zoo3:2181-zi reza2-p reza

谢谢，但我已经在accumul-env.sh中设置了Zookeeper。事实上，在“accumulo init”期间，它会找到Zookeeper并能够连接到它。我甚至试过“shell-u root-zh localhost:2181-zi reza——password reza”，但最终还是被困在了同一个地方。谢谢，但从我的原始帖子中可以清楚地看到，我完成了这两个步骤。你启动了所有步骤，然后初始化Accumulo了吗？您采取的步骤顺序尚不清楚。您是否像乔治所说的那样，通过显示器验证Accumulo似乎已启动？（其中监视器主机在/etc/accumulo/conf/monitors中定义）。您应该看到有关主服务器以及TabletServer的详细信息。tabletserver可能由于某种原因无法启动（常见问题是内存大小配置不正确和/或缺少正在生成的本机映射--请运行/usr/hdp/2.2.0.0-2041/accumulo/bin/build-native-library.sh以执行此操作）
