Failed to Start SAM

yjiang — Tue, 21 Apr 2026 12:22:47 GMT

Hi,

I installed HDF3.0 on an existing HDP2.6.0 cluster using Ambari 2.5.1. Installation was succeed, but failed to start SAM. My configuration uses Postgresql for SAM. I got the below error. Does anyone happen to see this before?

Hi,

I have exactly the same situation. Haven't find the solution yet.

Experiencing same issue on a completely new installation. We did notice that the postgres database did contain tables, so connection is working.

This message is usually because you are using an unsupported database version, most commonly because you installed SAM against the Ambari Database - unfortunately at this time they do not support cross-compatible versions.

For your reference, the support matrices are here: https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.0.0/bk_support-matrices/content/ch_matrices-hdf.html

After re-configured SAM against Postgresql 9.6, this error is gone. However, I got another error while starting SAM.

After manually executed /usr/hdf/current/streamline/bootstrap/sql/postgresql/create_tables.sql, I was able to start SAM successfully.

@yjiang

Glad to hear it's working - there should be a couple of bash scripts in /usr/hdf/current/streamline/bootstrap that are better to use than the sql directly - as it also creates the UDFs and roles and whatnot. I'd suggest you run ./bootstrap-storage.sh drop-create and then ./bootstrap.sh to ensure you have a clean install.

Thanks @Dan Chaffelson

Executed the scripts without error. Was able to start SAM and import an application. Cool!
