Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.There was an unexpected error (type=Internal Server Error, status=500).
com.tableausoftware.tabadmin.webapp.exceptions.RestException: org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss





我们看到上面的关键提示是Native memory allocation (mmap) failed to map,通过这里我们可以看到有用的线索,同时根据log日志进一步查找原因。
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 702021632 bytes for committing reserved memory.
# Possible reasons:
#   The system is out of physical RAM or swap space
#   In 32 bit mode, the process size limit was hit
# Possible solutions:
#   Reduce memory load on the system
#   Increase physical memory or swap space
#   Check if swap backing store is full
#   Use 64 bit Java on a 64 bit OS
#   Decrease Java heap size (-Xmx/-Xms)
#   Decrease number of Java threads
#   Decrease Java thread stack sizes (-Xss)
#   Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.

此类问题的首选推荐是重启server,方法是使用tsm restart命令。不过重启后,所有进程依然无法使用,tsm状态显示error,后台服务均未启动。
此时需要进一步查看日志文件,Tableau server的日志保存在以下路径中:


首先查看负责tsm命令的tabadmincontroller_node1-0日志文件,发现一切正常,没有error类的提示;由于上面提到了zookeeper,之后查看负责协调服务的日志,appzookeeper_node1-0.log 日志,反复记录的error问题为:
2019-07-14 21:01:37.130 +0800 29300 main : ERROR org.apache.zookeeper.server.quorum.QuorumPeerConfig – Invalid configuration, only one server specified (ignoring)
