[jira] [Updated] (HAWQ-1627) Support setting the max protocol
message size when talking with HDFS
[ https://issues.apache.org/jira/browse/HAWQ-1627?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hongxu Ma updated HAWQ-1627:
----------------------------
Description:
Now, the max size of protocol message in libhdfs is 64MB, and it cannot be adjusted.
When the max size is reached (accessing a very big HDFS table/file), will see the following lines in hawq master log:
