Yuanbo Liu created HDFS-10593:
---------------------------------
Summary: MAX_DIR_ITEMS should not be hard coded since RPC buff
size is configurable
Key: HDFS-10593
URL: https://issues.apache.org/jira/browse/HDFS-10593
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Yuanbo Liu
In HDFS, "dfs.namenode.fs-limits.max-directory-items" was introduced in
HDFS-6102 to restrict max items of single directory, and the value of it can
not be larger than the value of MAX_DIR_ITEMS. Since "ipc.maximum.data.length"
was added in HADOOP-9676 and documented in HADOOP-13039 to make maximum RPC
buffer size configurable, it's not proper to hard code the value of
MAX_DIR_ITEMS in {{FSDirectory}}.
