    We are facing this error while uploading a big model jar to be used via PMML API.Looks like there is a limit in place which is restricting the jar uploading to 50 MB or so per file.

    Can you confirm if this is a configuration that can be changed or will require code changes in the engine. This was working in ver 1.0.3 post a fix by Pokuri, but not working post upgrade to 1.1 release.

    We have a planned go-live event for tomorrow and hence would appreciate any quick help. Below is the stack trace.

    The max size allowed into Hbase column is controlled from Kamanja code.

    src code file: KeyValueHBase.scala
    src line: config.setInt(“hbase.client.keyvalue.maxsize”, 419430400);

    Will let the engineering team to weigh in the pros/cons of making the change, testing, and cutting a RC version.

    In 1.1 (on the master branch), we have the following line (line 158 of KeyValueHbase.scala).

    config.setInt(“hbase.client.keyvalue.maxsize”, getOptionalField(“hbase_client_keyvalue_maxsize”, parsed_json, adapterSpecificConfig_json, “104857600”).toString.trim.toInt);

    This allows for up to 100mb files to be uploaded by default. I have tested this using 75mb, 100mb, and 105mb files (the 105mb file failed to upload).

    If you need a larger file uploaded than 100mb, you can add the following line to your MetadataAPIConfig.properties file:


    This will set the max size for hbase to 400mb. I tested this locally and I am able to upload files as large as 400mb.

    As to why it’s failing to upload a 50mb file, I’m not sure. Version 1.1 contains the code necessary to perform this operation. Are you certain it’s 1.1 you’re on? I took a look at the line number of MetadataAPIImpl.scala:1313 and the exact def UploadJarsToDB isn’t there. Instead, UploadJarToDB (notice the lack of plurality), is there instead. The catch statement for UploadJarsToDB (plurality is back) is on line 1292.

      Just a reminder this forum is the right place to post and get all issues resolved. This is our first line of support available 24-by-7 and monitored by engineerings teams from different time zones.
