Nanda kumar updated HDFS-12991: ------------------------------- Summary: Ozone: Service Discovery: Limit the number of datanodes (REST servers) returned by KeySpaceManager#getServiceList call (was: Ozone: Service Discovery: Limit number of datanodes (REST servers) returned by KeySpaceManager#getServiceList call) > Ozone: Service Discovery: Limit the number of datanodes (REST servers) > returned by KeySpaceManager#getServiceList call > ---------------------------------------------------------------------------------------------------------------------- > > Key: HDFS-12991 > URL: https://issues.apache.org/jira/browse/HDFS-12991 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ozone > Reporter: Nanda kumar > Priority: Major > > To limit the number of datanodes (REST servers) returned by > KeySpaceManager#getServiceList call we should use {{ozone.rest.servers}} > property. The value for this property can be configured in the following 3 > ways. > * List of machines > Expressed as a hostname/IP of the machine followed by one or more machines > which are comma separated. > * IP/netmask notation > Single value that looks like 192.234.200.0/255.255.255.0, In this only > nodes with the matching IP address specified by this netmask will appear. > * Regular expression which matches hostname > This acts as a filter on the hostnames - For example datanode\[9?\].xxx.com > - will expose only datanodes that are named > datanode90,datanode91..etc(assuming datanodes are numbered using decimal in > this example) nodes. > These node lists are exposed if and only if they are healthy by default. > All these three different forms are mutually exclusive and we will flag an > error if more than one form is specified. > If the property is missing or if the value is empty, KSM will return all > datanodes that are healthy. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
