May 26, 2017. Outofmemoryexception Java. An unhandled exception of type 'System.OutOfMemoryException' occurred in System.ServiceModel. C# - serialize object to JSON format using JavaScriptSerializer.

JavaSerializerInstance.serialize(JavaSerializer.scala:73) at org.apache.spark.executor. I don't know how much memory you gave it, but if your machines have 512MB memory (total?) a 250MB data set, accounting for Java overhead, probably blows.

I Fill a dataset by sql query and the dataset contains a large datatable. DataSet dataSet1 = new DataSet(); SqlDataAdapter ndaGlobalClass = new SqlDataAdapter(Query, cn); ndaGlobalClass.SelectCommand.CommandTimeout = 0; cn.Open(); ndaGlobalClass.Fill(dataSet1); cn.Close(); string s=JsonConvert.SerializeObject(dataSet1.Tables[0]); the Query return a large datatable and when i convert it to json by serializing System.OutOfMemoryException' was thrown. How can i fix this problem? I need to serialize large datatable and there is no circular issue. If you are using a large data table and you are getting out of memory issues, it may well be that the size of the JSON string is just too big for.NET - there is a limit of 2GB on any single object in.NET, and since JSON is a text-based serialization a large table could well exceed that even if the 'raw' data table is considerably less than that.

Try an experiment: find out how many rows the table holds, and modify your query to return only half that: SELECT TOP nnn should do it. Then see if you can convert that to JSON and if so how big the resulting string is.

That should give you an idea if this is just getting a bit silly size wise, and you might be better off finding a different way to transfer the data!:laugh.

Hi Sree, You can set JVM flags by setting the flags environment variable before running the CLI. For example: export flags='-Xmx2048m' kite-dataset. - or - flags='-Xmx2048m' kite-dataset. The environment variables you can use to configure the CLI are documented here: -Joey >-- >You received this message because you are subscribed to the Google Groups >'CDK Development' group. >To unsubscribe from this group and stop receiving emails from it, send an >email to. >For more options, visit. -- Joey Echeverria Senior Infrastructure Engineer Ryan Blue 01.06.15 08:56.

Joey's fix is a good one if you have the memory for it, but another work-around is to put the file you're importing in HDFS. Then we will use a MR job that doesn't have the memory problem. The cause of this problem is that we were using Crunch's MemPipeline for local files, which will only run one stage at a time and will keep everything in memory.

So it will do the conversion, keeping all records in memory, and then write them to disk. This is CDK-898 [1]. We're fixing this in 1.1.0 and using the LocalJobRunner rather than a MemPipeline. That will run copy or import tasks from local data as they would run on a cluster, which uses much less memory. Rb [1]: -- Ryan Blue Software Engineer Cloudera, Inc. Sree Pratheep 01.06.15 22:50.

Hi Sree, Looks like there's something wrong with the 'flags' variable we need to fix. Sorry about that. Did you try running with the file in HDFS instead of on local disk? I think that is another way to fix this.

We got the following error. Sree, I would verify that the ojdbc.jar is actually in the location. I ran into this same issue and the jar was not there. I fixed this by downloading the jar from oracle and putting it in the expected location. This however didn't resolve my issues as I then ran into the CopyTask job failing job failure(s) occurred: org.kitesdk.tools.CopyTask: Kite(dataset:hdfs://.

How else would a file you can list not exist, right? I'd look into that file more. Kite adds Hive to the distributed cache by adding everything in the Hive lib directory. If it finds a broken symlink, then it makes sense that it would fail. I think it should work without ojdbc6.jar so you might be able to simply remove the symlink. The problem with that approach is that a broken symlink indicates some other issue that you should also look into. Maybe you need another package installed that provides it, or maybe the Hive package you're using has a bug.

I'd contact your Hadoop vendor to find out, and please let us know on this list what you find so others can get past this problem.

I'm not sure what's happening with your setup, but I think you might have a problem with your install like Rafi. I don't think these files should be missing.
