------------------------------
Summary: separate replication config for client to create a file
or set replication
Key: HDFS-9105
URL: https://issues.apache.org/jira/browse/HDFS-9105
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Chang Li
Assignee: Chang Li
one scenario when we want this new config: we want to enforce min replication
of value 2, when client try to create a file, it's check against the
replication factor of the new config, which is set to 2, so that client can
not create a file of replication of 1. But when client try to close file and
there are some datanode failures in the pipeline and only 1 datanode remain, it
is checked against old minReplication value, which has value 1, so we will
allow client to close the file.
