本文详细解析了Hive服务启动时遇到的异常问题，主要原因是由于加载了HBase的lib文件夹中的包导致的字符编码集加载错误。通过分析异常堆栈信息，定位到问题所在，并提供了具体的解决方法，即在启动Hive时使用--skiphbasecp参数来避免加载HBase的类路径。

环境说明

hadoop-2.7.4
hive-2.3.2
hbase-1.4.2
jdk1.8.0_161

问题现象
原先启动hiveserver2和metastore的两个服务一直运行状况良好，重启这个两个服务后都出现如下异常信息

启动命令示例:hive --service hiveserver2

定位过程：
1.根据异常堆栈的信息，初步判断是在java进程启动时加载字符编码集时找不到具体lib中的类方法；
2.CharsetProviderICU这个编码集提供方不是jdk自带的(在jdk的lib中搜了下没找到)，于是查看jdk的源码查看这个类的加载过程
Charset.java:340

 ClassLoader cl = ClassLoader.getSystemClassLoader();
 ServiceLoader<CharsetProvider> sl = ServiceLoader.load(CharsetProvider.class, cl);
 Iterator<CharsetProvider> i = sl.iterator();

ServiceLoader中的load过程核心代码摘录如下

try {
    String fullName = PREFIX + service.getName();
    if (loader == null)
        configs = ClassLoader.getSystemResources(fullName);
    else
        configs = loader.getResources(fullName);
} catch (IOException x) {
     fail(service, "Error locating configuration files", x);
}

其中PREFIX定义为

private static final String PREFIX = "META-INF/services/";

所以可以想到CharsetProviderICU加载的描述应该是定义在某个jar下面的META-INF/services/xxxx的描述中，但是我在hive的lib下并没有查找到CharsetProviderICU这个类的存在；
3.于是再到hbase的lib文件下去查找CharsetProviderICU看是否存在,显示在phoenix-4.14.0-HBase-1.4-client.jar中存在，如果在hive的classpath中确实加载了phoenix-4.14.0-HBase-1.4-client.jar，那就可以理解报错的原因，由于phoenix引入后hive的服务一直没有重启，所以没有报错；
4.现在亟待解决的问题的在启动hive的时候为什么会去加载hbase lib文件夹的包，查看hive的启动脚本(bin/hive这个文件)，有如下一段描述

if [ "$SKIP_HBASECP" = false ]; then
  # HBase detection. Need bin/hbase and a conf dir for building classpath entries.
  # Start with BigTop defaults for HBASE_HOME and HBASE_CONF_DIR.
  HBASE_HOME=${HBASE_HOME:-"/usr/lib/hbase"}
  HBASE_CONF_DIR=${HBASE_CONF_DIR:-"/etc/hbase/conf"}
  if [[ ! -d $HBASE_CONF_DIR ]] ; then
    # not explicitly set, nor in BigTop location. Try looking in HBASE_HOME.
    HBASE_CONF_DIR="$HBASE_HOME/conf"
  fi
 
  # perhaps we've located the HBase config. if so, include it on classpath.
  if [[ -d $HBASE_CONF_DIR ]] ; then
    export HADOOP_CLASSPATH="${HADOOP_CLASSPATH}:${HBASE_CONF_DIR}"
  fi
 
  # look for the hbase script. First check HBASE_HOME and then ask PATH.
  if [[ -e $HBASE_HOME/bin/hbase ]] ; then
    HBASE_BIN="$HBASE_HOME/bin/hbase"
  fi
  HBASE_BIN=${HBASE_BIN:-"$(which hbase)"}
 
  # perhaps we've located HBase. If so, include its details on the classpath
  if [[ -n $HBASE_BIN ]] ; then
    # exclude ZK, PB, and Guava (See HIVE-2055)
    # depends on HBASE-8438 (hbase-0.94.14+, hbase-0.96.1+) for `hbase mapredcp` command
    for x in $($HBASE_BIN mapredcp 2>> ${STDERR} | tr ':' '\n') ; do
      if [[ $x == *zookeeper* || $x == *protobuf-java* || $x == *guava* ]] ; then
        continue
      fi
      # TODO: should these should be added to AUX_PARAM as well?
      export HADOOP_CLASSPATH="${HADOOP_CLASSPATH}:${x}"
    done
  fi
fi

关键的语句是 hbase mapredcp 2>> ${STDERR} | tr ':' '\n'列出了与hbase运行时所需的各种jar包，并在下面加载进了hive运行时所需的classpath中，所以这就解释了hive运行时为什么会加载hbase的lib

解决方法:
按照hive启动脚本中的命令参数--skiphbasecp,如果设置为true则不会记载到classpath路径中，所以启动命令修改为
