Hadoop Cloudera CDH上的Impala“无法创建日志文件：权限被拒绝”

我通过Cloudera Manager 4.5中的一个包在CDH 4.2.0-1.cdh4.2.0.p0.10集群上安装了Impala

当我尝试启动服务时，所有节点上的服务都会失败，并显示此消息

    perl -pi -e 's#{{CMF_CONF_DIR}}#/run/cloudera-scm-agent/process/800-impala-IMPALAD#g' /run/cloudera-scm-agent/process/800-impala-IMPALAD/impala-conf/impalad_flags
    '[' impalad = impalad ']'
    exec /opt/cloudera/parcels/IMPALA-0.6-1.p0.109/lib/impala/../../bin/impalad --flagfile=/run/cloudera-scm-agent/process/800-impala-IMPALAD/impala-conf/impalad_flags

我不确定权限问题是否是导致Impala未运行的原因，或者是因为无法写入崩溃日志而导致其他崩溃和权限问题

任何帮助都会很好

从调试二进制文件运行impala，如下所述：

似乎与内核12.04.1 LTS中的JVM有关
