Launch distcp
Authenticate using kinit
on the client and then launch the
distcp
job.
Consider the following
example:
hadoop distcp hdfs://xyz01.dev.example.com:8020/user/alice hdfs://abc01.qa.example.com:8020/user/alice
If launching
distcp
fails, force Kerberos to use TCP instead of UDP by
adding the following parameter to the krb5.conf
file on the
client:[libdefaults]
udp_preference_limit = 1
