gohadoop is native go clients for Apache Hadoop YARN.
It includes an early version of Hadoop IPC client and requisite YARN client libraries to implement YARN applications completely in go (both YARN application-client and application-master).
- Set HADOOP_CONF_DIR environment variable, and ensure the conf directory contains both *-default.xml and *-site.xml files.
- Currently the go hadoop IPC client doesn't support secure Hadoop IPC (SASL). As a result, you'll need to apply patches/gohadoop.patch to switch off the default token-auth in effect for YARN applications. Also, you'll need to set yarn.rpc.auth to false in yarn-site.xml.
- hadoop_yarn/examples/dist_shell is an example go YARN application: client.go is the submission client and applicationmaster.go is the application-master.
HADOOP_CONF_DIR=conf go run hadoop_yarn/examples/dist_shell/client.go
