2.1. Getting Correct Configuration Values for Manually-Deployed Clusters

If you have manually deployed your cluster, you must enter cluster configuration values in the Pig View Create Instance page. The following table explains where you can find cluster configuration settings in Ambari.

Table 6.1. Finding Cluster Configuration Values for the Pig View in Ambari

Property	Value
Scripts HDFS Directory*	`/user/${username}/pig/scripts`
Jobs HDFS Directory*	`/user/${username}/pig/jobs`
WebHDFS FileSystem URI*	Click HDFS > Configs > Advanced hdfs-site > dfs.namenode.http-address. When you enter the value in the view definition, pre-pend "webhdfs://" to the value you find in the advanced HDFS configuration settings. For example, `webhdfs://c6401.ambari.apache.org:50070`
WebHCat Hostname*	Click Hive > Configs > Advanced > WebHCat Server > WebHCat Server host to view the hostname. For example, `c6402.ambari.apache.org`
WebHCat Port*	Click Hive > Configs > Advanced > Advanced webhcat-site > templeton.port to view the port number. For example, `50111`

For NameNode High Availability

The following values must be entered for primary and secondary NameNodes:

Table 6.2. Pig View Settings for NameNode High Availability

Property	Value
First NameNode RPC Address or Second NameNode RPC Address	Select the primary or secondary NameNode to view settings from that host in the cluster. See how to get the NameNode RPC address. When you enter the value in the view definition, pre-pend "http://" to the value you find in the advanced `hdfs-site` settings. For example, `http://c6401.ambari.apache.org:8020`
First NameNode HTTP (WebHDFS) Address or Second NameNode HTTP (WebHDFS) Address	Click HDFS > Configs > Advanced > Advanced hdfs-site > dfs.namenode.http-address. When you enter the value in the view definition, pre-pend "http://" to the value you find in the advanced `hdfs-site` settings. For example, `http://c6401.ambari.apache.org:50070`

To get First NameNode RPC Address values:

Navigate to the HDFS service page in Ambari that contains links to individual NameNodes. Click NameNode (primary) or SNameNode (secondary) to view the host page:

Figure 6.3. HDFS Service Page in Ambari
On the host page, click Configs > Advanced.
Enter "rpc" in the Filter search well at the top right corner of the page or navigate to the Advanced hdfs-site settings to find the dfs.namenode.rpc-address value that you can enter into the Pig View definition. Here is an example of using the Filter to locate a value:
