spring-batch

I was trying the spring batch word count program and faced a version issue like this : ERROR [org.springframework.batch.core.step.AbstractStep] - <Encountered an error executing the step> java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.Counter, but class was expected I use Cloudera Hadoop2 cdh4.5.0 and Spring hadoop version 1.0.1.RELEASE . I cant identify the exact problem as Spring batch is compatible with hadoop cdh4 . My dependency tree is as shown below. [INFO] org.springframework.data:batch-wordcount:jar:0.0.1 [INFO] +- org.springframework:spring

I'm using a tasklet and a StepExecutionListener but it seems there's no listener callback for a case where my tasklet throws an exception. For various other listener types – ChunkListener , ItemProcessListener , etc. – there is but none of those listeners work with tasklets. All I want is an event after my tasklet executes regardless of whether it threw an exception or not. Is it possible to do that? It doesn't appear to be supported in the API. Edit: Responding to @danidemi I'm registering the listener and tasklet using the programmatic API like this: steps.get(name) .listener(listener)

I'm working on an app that extract records from an Oracle database and then are exported as one single tabulated file. However, when I attempt to read from the DB using JdbcPagingItemReader and write to a file I only get the number of records specified in pageSize. So if the pageSize is 10, then I get a file with 10 lines and the rest of the records seem to be ignored. So far, I haven't been able to find whats is really going on and any help would be most welcome. Here is the JdbcPagingItemReader config: <bean id="databaseItemReader" class="org.springframework.batch.item.database

I want to send a list from rest client to rest web service which will start a job in Spring Batch. Is that possible or must I save the list in database/flatfile before start the job and read the input values from database/flatfile? I guess someone pointed how do it in certain Jira issue (see below) but I couldn't figure out at least a basic idea how to move forward. I placed below my controller and how I am trying to cast it to JobParameter. I placed the Jira link and the possible direction perhaps I should take but I really didn't understand the suggestion in this Jira issue. I added below

with Spring Batch xml based configuration you can parameterize the commit-interval / chunk size like: <job id="basicSimpleJob" xmlns="http://www.springframework.org/schema/batch"> <step id="basicSimpleStep" > <tasklet> <chunk reader="reader" processor="processor" writer="writer" commit-interval="#{jobParameters['commit.interval']}"> </chunk> </tasklet> </step> </job> with javaconfig based configuration it could look like @Bean public Step step( ItemStreamReader<Map<String, Object>> reader, ItemWriter<Map<String, Object>> writer, @Value("#{jobParameters['commit.interval']}") Integer

I have a file as an input which contain a json Array : [ { ..., ... }, { ..., ... }, { ..., ... } ] I want to read it without breaking the spring batch principales (With the same way as FlatFileReader or XmlReader) I didn't find any way to do it the readers already implemented in spring-batch . What's the best way to implement this reader ? Thanks in Advance Assuming you want to model the StaxEventItemReader in that you want to read each item of the JSON array as an item in Spring Batch, here's what I'd recommend: RecordSeparatorPolicy - You'll need to implement your own RecordSepartorPolicy
