Hello All,
i have a very simple job design to extract data from oracle DB to tparquetoutput
file created and put fine using local directories , when i try to put the file on HDFS path , job terminated with errors based on some changes i do in the job
1-mark check button for use external
hadoop dependencies , and path as below
"hdfs://Z****-dev/user/devtest/talendtest/BI_.parquet"
job failed with error : UnknownHostException: Z****-dev
2-try to run the job and remove namenode from file path , job finished but file created on the local directory not HDFS
any support on this ?
Hi @muhamd shafeeq
It seems "Z****-dev" host name is not recognized by the machine you're executing the Job.
Are you able to ping this hostname? Or perhaps try replacing its name by IP address on tFileOutputParquet.
Hello @muhamd shafeeq ,
To fix the error UnknownHostException, it's required to add the ip and hostname on the below file
1) Run on windows
C:\Windows\System32\drivers\etc\hosts
x.x.x.x Z****-dev
2) Run on Linux
/etc/hosts
x.x.x.x Z****-dev
Best regards
Aiming
