I have a file in HDFS named AccountManager_S00B26_291141_NBMorbidity_2018-10-0201_17_32.258_TriggerFile.txt
2018-10-0201_17_32.258 in the above file name is random that needs to be ignored while deleting.
I tried the below code. But, It didn't work
val hadoopConf = new Configuration()
val hdfs = FileSystem.get(hadoopConf)
val src = new Path("AccountManager_S00B26_291141_NBMorbidity_{[0-9_.-]}*_TriggerFile.txt")
hdfs.delete(src,true)
regex scala hadoop hdfs

You'll need to list all files of the parent directory, iterate, check, then delete the matches.Pathdoesn't accept patterns

Not really. You're already getting the filesystem, and there's just one method you're missing to list all files

You'll need to list all files of the parent directory, iterate, check, then delete the matches.Pathdoesn't accept patterns
