如何使用influxdb作为flink metrics reporter

我按照官网所介绍的flink metrics reporter设置，选用了influxdb，进行了如下设置： metrics.reporter.influxdb.class:org.apache.flink.metrics.influxdb.InfluxdbReportermetrics.reporter.influxdb.host:localhostmetrics.reporter.influxdb.port:8086metrics.reporter.influxdb.db:flinkmetrics.reporter.influxdb.username:flink-metrics metrics.reporter.influxdb.password:qwerty metrics.reporter.influxdb.retentionPolicy:one_hour 但是，启动flink作业（on yarn per job模式）和flinxdb后，发现一直报错： error [500] - "retention policy not found: one_hour" {"log_id": "OK6nejJI000", "service": "httpd"} [httpd] 10.90.. - flinkuser [03/Jan/2020:19:35:58 +0800] "POST /write? db=flink&rp=one_hour&precision=n&consistency=one HTTP/1.1" 500 49 "-" "okhttp/3.11.0" 3637af63-2e1d-11ea-802a-000c2947e206 165

我使用的是 flink 1.9.1，influxdb版本是1.79.

而且，当我不设置retentionPolicy时，还是会报错，提示： org.apache.flink.metrics.influxdb.shaded.org.influxdb.InfluxDBException$UnableToParseException: partial write: unable to parse "taskmanager_job_task_operator_sync-time-avg,host=master,job_id=03136f4c1a78e9930262b455ef0657e2,job_name=Flink-app,operator_id=cbc357ccb763df2852fee8c4fc7d55f2,operator_name=XXX,task_attempt_num=0,task_id= cbc357ccb763df2852fee8c4fc7d55f2,task_name=XX,tm_id=container_1577507646998_0054_01_000002 value=? 1578051247605000000": invalid boolean*来自志愿者整理的flink邮件归档
