Subject Re: [Issue]Ambari HDFS parameters configuration checking errors in HAWQ 2.0.0.0 with HDP 2.4.2.0-258
Date Sat, 17 Dec 2016 13:36:22 GMT
Hi,

4.In http://hdb.docs.pivotal.io/200/hdb/install/install-cli.html & "hawq
check"

net.ipv4.ip_local_port_range = 1281 65535


While in Ambari,
sysctl.net.ipv4.ip_local_port_range = 1025 65535


5. I did not find a proper interface for submitting issues to Apache HAWQ
JIRA. Any hint?



Best regards,
