flink1.10 stop with a savepoint失败

LiangbinZhang
普通的source -> map -> filter-> sink 测试应用。

触发savepoint的脚本 ：
    ${FLINK_HOME} stop -p ${TARGET_DIR} -d ${JOB_ID}
具体报错信息：

org.apache.flink.util.FlinkException: Could not stop with a savepoint job
"81990282a4686ebda3d04041e3620776".

查看报错，怀疑是权限问题，我是root用户启动的应用，savepoint目录所在的hdfs路径权限所属也是root，如果不停止应用，直接触发savepoint没问题，继续定位到是root用户去停止hadoop
应用遇到权限问题，但是不知道怎么解决，目前卡在这里。

Re: flink1.10 stop with a savepoint失败

Congxian Qiu
Hi
    你可以看下 JM log 中这个 savepoint 失败是什么原因导致的，如果是 savepoint 超时了，就要看哪个 task
完成的慢，（savepoint 可能比 checkpoint 要慢）
Best,
Congxian

Hi,Congxian
    感谢提供思路，看了一下，JM端没有暴露日志，只能查看到ck正常的日志

Best,
Robin
