There are 4 missing blocks. The following files may be corrupted

Please check the logs or run fsck in order to identify the missing blocks. See the Hadoop FAQ for common causes and potential solutions.

步骤1，检查文件缺失情况

hadoop fsck /tmp/logs/root/logs-tfile/ | grep parquet

可以看到

blk_1073755509 /spark-history/application_1703488625044_0273_1
blk_1073758750 /tmp/logs/root/logs-tfile/application_1703488625044_0273/hadoop03_37847
blk_1073758751 /tmp/logs/root/logs-tfile/application_1703488625044_0273/hadoop02_41829
blk_1073758752 /tmp/logs/root/logs-tfile/application_1703488625044_0353/hadoop03_37847

确实各自都丢失了1个Block， 文件已经损坏，不可恢复。

步骤2，删除缺失文件

因为我的环境为测试环境，可删除缺失文件，生产环境还需要斟酌判断。

hdfs fsck -delete  /spark-history/application_1703488625044_0273_1
 
hdfs fsck -delete  /tmp/logs/root/logs-tfile/application_1703488625044_0273/hadoop03_37847
 
hdfs fsck -delete  /tmp/logs/root/logs-tfile/application_1703488625044_0273/hadoop02_41829
 
hdfs fsck -delete  /tmp/logs/root/logs-tfile/application_1703488625044_0353/hadoop03_37847

步骤3， 检查集群健康状况
