Context: Loading and streaming Excel file as Flux. Processing Flux records and inserting them into database using R2DBC.
implementation("org.apache.poi:poi:4.1.2") - apache lib which has excel domain of workbooks/sheets/rows/cells
implementation("org.apache.poi:poi-ooxml:4.1.2")
implementation("com.monitorjbl:xlsx-streamer:2.1.0") - streamer wrapper which avoids loading entire excel file into the memory and parses chunks of a file
Converting file to Flux (extract header as first row and then glue it to every subsequent event/row coming from Flux):
override fun extract(inputStream: InputStream): Flux<Map<String, String>> {
val workbook: Workbook = StreamingReader.builder()
.rowCacheSize(10) // number of rows to keep in memory (defaults to 10)
.bufferSize(4096) // buffer size to use when reading InputStream to file (defaults to 1024)
.open(inputStream)
val xsltRows = Flux.fromIterable(workbook).flatMap { Flux.fromIterable(it) }
return xsltRows.next()
.map { rowToHeader(it) }
.flatMapMany { header -> xsltRows.map { combineToMap(header, it) } }
}
Subsequently I process this Flux into domain models for Spring R2DBC repositories and insert the entries into MySQL database.
The problem: I am missing a single Excel row (out of roughly 2 k). It is always the same row, but nothing special about data in this row.
Recall combineToMap method that associates name from the header with every cell value, it also prints the row logical sequence number as in the file:
private fun combineToMap(header: Map<Int, String>, row: Row): Map<String, String> {
val mapRow: MutableMap<String, String> = mutableMapOf()
val logicalRowNum = row.rowNum+1
logger.info("Processing row: $logicalRowNum")
for (cell in row) {
if (cell.columnIndex >= header.keys.size) {
continue
}
val headerName = header[cell.columnIndex].takeUnless { it.isNullOrBlank() }
?: throw IllegalStateException("No header name for ${cell.columnIndex} column index for header " +
"$header and cell ${cell.stringCellValue} row index ${row.rowNum}")
mapRow[headerName] = cell.stringCellValue
mapRow["row"] = logicalRowNum.toString()
}
return mapRow
}
When I added the log line I noticed the following:
2020-11-22 15:49:56.684 INFO 20034 --- [ Test worker] c.b.XSLXFileRecordsExtractor : Processing row: 255

2020-11-22 15:50:02.608 INFO 20034 --- [tor-tcp-epoll-1] c.b.XSLXFileRecordsExtractor : Processing row: 261
Note that the scheduler is switched after 257 row, during the switch I lost 258 row. The pool:
tor-tcp-epoll-1
is understand is Spring R2DBC internal pool.
In my downstream, if instead of doing repository.save I return static Mono.just(entity) I get my 258 row back, notice the scheduler wasn't switched as well.
2020-11-22 16:01:14.000 INFO 21959 --- [ Test worker] c.b.XSLXFileRecordsExtractor : Processing row: 257

2020-11-22 16:01:14.009 INFO 21959 --- [ Test worker] c.b.XSLXFileRecordsExtractor : Processing row: 259
Is this a problem with the Excel libraries or my implementation? Why am I losing the record when TP is switched?
P.S. I am not specifying any schedulers or parallel blocks or anything to mess with threads anywhere in my flow apart from calling Spring R2DBC repositories.
I will attempt to rewrite using implementation("org.apache.commons:commons-csv:1.8") and observe if same happens, but if anyone can spot anything obvious or experienced similar elsewhere, I would be infinitely grateful.
In the end I switched to commons-csv which does not have the same problem:
2020-11-22 18:34:03.719 INFO 15733 --- [ Test worker] c.b.CSVFileRecordsExtractor : Processing row: 256
2020-11-22 18:34:09.062 INFO 15733 --- [tor-tcp-epoll-1] c.b.CSVFileRecordsExtractor : Processing row: 257
2020-11-22 18:34:09.088 INFO 15733 --- [tor-tcp-epoll-1] c.b.CSVFileRecordsExtractor : Processing row: 258
For original approach, I tried to publish all on one scheduler for xlsx-streamer and poi , even forced Spring R2DBC to publish on the same single thread scheduler and it still skipped the record.
What I could observe is that when database callbacks start to come regardless of which thread pool, this is exact moment when the record gets lost , seems that iterator context gets broken.
I mean the xslx library never claimed to be reactive so no expectations there.
I am writing to an MQ queue from Java and I am intermittently get the error response below. I am using IBM MQ version 9.
What could be the cause of this as its intermittent and the queue / queue manager being written to exists and was running during this time.

Most likely the cause will be logic flow related with variables or objects falling out of scope, then coming back into scope with reset / default values.
The traces that you are running, will tell you which values your code is actually using. You will most likely need to add logging into your application to determine why the values are being lost.
I am following the NiFi 1.10 stateless guildeline to create a simple process group of executing a sql in mysql db. I have put necessary parm of db controller service to parameter context.
it works well in nifi canvas. Then i add it to registry and prepare a json parm file: stateless-simpledb.json

Seems the apache nifi stateless function failed to set controller service even it's in "process group" scope.
Would anyone has any advice?
As mentioned in the comments, this appears to be a known problem with the validation of controller services.
This can be avoided by using Nifi 1.12 and above as it got fixed in the following jira: https://issues.apache.org/jira/plugins/servlet/mobile#issue/NIFI-7380
Though I am not entirely sure of this, it may also be possible that this simply indicates that your controller service is not configured correctly. This would be worth double checking.
I am running Cassandra and have about 20k records in it to play with. I am trying to run a filter in pig on this data but am getting the following message back:

You would think this is an obvious error, and believe me there are a ton of results on google for this. It's clear that some piece of my data isn't conforming to the expected type of a given column. What I don't understand is 1.) why this is happening, and 2.) how to debug it. If I try to insert invalid data into Cassandra from my nodejs app, it will throw this kind of error if my data type doesn't match the columns data type, which means that this shouldn't be possible? I've read that data validation using UTF8 is wonky and that setting a different kind of validation is the answer, but I don't know how to do that. Here are my steps to reproduce:
grunt> define CqlNativeStorage org.apache.cassandra.hadoop.pig.CqlNativeStorage();
grunt> test = load 'cql://blah/blahblah' USING CqlNativeStorage();
grunt> describe test;
13:09:54.544 [main] DEBUG o.a.c.hadoop.pig.CqlNativeStorage - Found ksDef name: blah

grunt> query1 = FILTER blahblah BY city == 'New York';
grunt> dump query1;
Then it runs for awhile and dumps out tons of logs and the error appears.
Discovered my problem: the pig partioner did not match CQL3, and therefore the data was being parsed incorrectly. Previously the environment variable was PIG_PARTITIONER=org.apache.cassandra.dht.RandomPartitioner. After I changed it to PIG_PARTITIONER=org.apache.cassandra.dht.Murmur3Partitioner it started working.
I want to try this new Flafka flow: only use kafka channel transfer data to hdfs sink. I tried it from kafka channel and logger sink which is easier to monitor. My configuration file is:
# Name the components on this agent
a1.sinks = sink1
a1.channels = channel1
a1.channels.channel1.type = org.apache.flume.channel.kafka.KafkaChannel
a1.channels.channel1.brokerList = localhost:9093,localhost:9094
a1.channels.channel1.topic = par4
a1.channels.channel1.zookeeperConnect = localhost:2181
a1.channels.channel1.parseAsFlumeEvent = false
a1.channels.cnannel1.kafka.consumer.timeout.ms = 1000000
a1.sinks.sink1.channel = channel1
a1.sinks.sink1.type = logger
I set up zookeeper and two brokers locally using above port number, and I have a producer client keep push messages to kafka.
I got following messages:

I don't understand why I have this unable to deliver event error. (I also tried to set up HDFS sink which gives me the same error.)
I also don't understand why I didn't successfully set consumer.timeout.ms
Looking for help, thanks!
