Question

我通过CDH 4.2.0-1.cdh4.2.0.p0.10群集中Cloudera Manager 4.5中的parcel安装了Impala。

当我尝试启动该服务时，它会在所有带有此消息的节点上失败

    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导致Impala未运行或是否有其他问题崩溃且权限问题刚刚出现，因为无法写入崩溃日志。

任何帮助都会很棒！

按照此处所述从调试二进制文件运行impala：

https://issues.cloudera.org/browse/IMPALA-160

似乎与内核12.04.1 LTS中的JVM有关
