1.查看hdfs文件的block信息
不正常的文件
hdfs fsck /logs/xxx/xxxx.gz.gz -files -blocks -locations Connecting to namenode via http://xxx-01:50070/fsck?ugi=xxx&files=1&blocks=1&locations=1&path=%2Flogs%2Fnsh%2Fjson%2F401294%2Fds%3D2019-07-14%2Fxxx.gz.gz FSCK started by xxxx (auth:KERBEROS_SSL) from /10.90.1.91 for path xxxxx.gz.gz at Mon Jul 15 11:44:13 CST 2019 Status: HEALTHY Total size: 0 B (Total open files size: 194 B) Total dirs: 0 Total files: 0 Total symlinks: 0 (Files currently being written: 1) Total blocks (validated): 0 (Total open file blocks (not validated): 1) Minimally replicated blocks: 0 Over-replicated blocks: 0 Under-replicated blocks: 0 Mis-replicated blocks: 0 Default replication factor: 3 Average block replication: 0.0 Corrupt blocks: 0 Missing replicas: 0 Number of data-nodes: 99 Number of racks: 3 FSCK ended at Mon Jul 15 11:44:13 CST 2019 in 0 milliseconds

2.修复hdfs文件命令
hdfs debug recoverLease -path /logs/xxxx.gz.gz -retries 3
修复之后
hdfs fsck /logs/xxx.gz.gz -files -blocks -locations Connecting to namenode via http://xxx-01:50070/fsck?ugi=xxx&files=1&blocks=1&locations=1&path=%2Flogs%2Fnsh%2Fjson%2F401294%2Fds%3D2019-07-14%2Fxxx.gz.gz FSCK started by xxx (auth:KERBEROS_SSL) from /10.90.1.91 for path /logs/xxxx.gz.gz at Mon Jul 15 11:48:01 CST 2019 /logs/xxxx.gz.gz 67157 bytes, 1 block(s): OK 0.
