Hi, I am trying to configure the 'libhdfs' in my CHD5.14.0 cluster but getting some issues. I have two node CDH-cluster and its working fine as I checked with TestDFSIO. I set the FIO_LIBHDFS_INCLUDE, FIO_LIBHDFS_LIB, 'hadoop classpath' in environment. Installed FIO on Master and configured it with enabling libhdfs while 'configure'. Created hdfs.fio file as [global] runtime=10 [hdfs] rw=read namenode=xx.xx.x.xxx hostname=server1 port=9000 hdfsdirectory=/tmp chunk_size=1m hdfs_use_direct=1 ioengine=libhdfs size=20m bs=256k single_instance=1 Ran the fio job(sudo fio hdfs.fio) which resulted into errors as fio-3.6-33-g540e Starting 1 process loadFileSystems error hdfsBuilderConnect forceNewInstance=0, nn=server1, port=9000, kerbTicketCachePath=(NULL), userName=(NULL) error hdfsExists: constructNewObjectOfPath error hdfs: invalid working directory /tmp: Unknown error 255 fio: failed to init engine data: 255 Run status group 0 (all jobs) I tried many things but could not configure libhdfs to work correctly with FIO on my CDH. Any suggestion would be appreciated! Thanks in advance. Note: /tmp directory is present at the hdfs level.
