BDM - infa_rpm.tar
About
This is a library file.
The first time a Hadoop Pushdown Mapping is executed, DIS upload the Informatica BDM Tar archive (infa_rpm.tar) to each node of the cluster.
During Startup of DIS, it calculates the MD5 value. If any EBF (patch) is applied on DIS, the MD5 value will be different and hence, it will regenerate the tarball again and transfer it to Hadoop Data node.
DIS will upload it to the HDFS Staging Directory where it will then installed on each node.
By default, the OS user running the DIS will upload the tar file.
If this user does not have any permissions on the HDFS Staging Directory specified on the DIS, it is possible to force the upload of files to be performed as a different user.
This can be done by configuring the “Hadoop Staging User”, which can be configured in the DIS properties.
