Description

iotdb版本0.13.0
现场环境iotdb集成hdfs,hdfs 3.1.4
问题描述:现场hdfs配置了kdc环境,集成hdfs用的是超级管理员hadoop用户,票据也是hadoop票据。kerberos有效期24小时。log_error.一直提示Caused by: org.ietf.jgss.GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)的异常。hadoop环境本身是没有问题的,其他业务可以正常使用。现场自查,怀疑可能是与hdfs集成部分的没有及时获取票据,导致票据过期。

Research direction

Start by reproducing the IoTDB 0.13.0 integration with Hadoop 3.1.4 HDFS in a Kerberos/KDC environment, using the configuration and log_error details from the issue. Trace the HDFS integration's ticket handling and confirm whether the Hadoop ticket is renewed after its 24-hour validity period. Done means the integration continues operating after ticket expiry without the reported GSSException.
