我在CDH 4.2.0-1.cdh4.2.0.p0.10集群上通过软件包在Cloudera Manager 4.5中安装了Impala。
当我尝试启动服务时，它在所有节点上都失败了，显示以下消息
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

完整的StdErr日志
我不确定权限问题是Impala不运行的原因，还是其他东西崩溃了，权限问题只是因为崩溃日志无法写入而出现的。
任何帮助将是伟大的!
按照下面的描述从调试二进制文件中运行impala:
https://issues.cloudera.org/browse/impala - 160似乎与内核12.04.1 LTS中的JVM有关
