flink savepoint 异常
本人用flink 1.10.1版本进行savepoint时遇到下列错误，暂时不清楚错误的原因，特来寻求帮助，麻烦大佬们看看
已经排除反压和重启的原因，checkpoint超时设置了十分钟，conf配置增加客户端连接master的时间，但还是出现异常。
命令
flink savepoint -yid application_1604456903594_2381
fb8131bcb78cbdf2bb9a705d8a4ceebc
hdfs:///hadoopnamenodeHA/flink/flink-savepoints
异常
The program finished with the following exception:
org.apache.flink.util.FlinkException: Triggering a savepoint for the job

Hi
异常信息中有 “Failed to trigger savepoint. Failure reason: An Exception
occurred while triggering the checkpoint.” 或许你可以看看 JM 的日志，找一下看看有没有什么详细日志
Best,
Congxian
