Dear all,
I am currently writing an open source library for reading/writing office
files on Hadoop/Spark/Hive/etc. The code is on Github and an official
release in form of a library on maven central will follow soon.
The Excel files will be supported by the Apache POI library (3.15).
So far everyt
There is already a bug report, see my message.

Dear all,
I released a first version of an open source library that uses Apache POI
to read/write Excel files on Hadoop/Spark/etc.:

Only 3.16 supports encryption for HSSF. You have to wait until it is released
to get a stable version.

Might be that one dependency loads a different version of the parser?

Are you using a build tool (gradle, maven,?)? If so can you please post the
build script?
Without a build tool you will always get these kinds of messages for any
library.

Is it sure to be related to Apache POI or some of your own code?
Have you configured Input and Outputbuffers correctly?
Are all input and outputstreams closed? Is there maybe an exception that you do
not log? Is it a multi-thread environment and threads are isolated from each
other ?

Have you tried another file? How was this file created? Maybe it is broken in a
very weird way.

I personally use the workbook factory to open encrypted documents:
this.currentWorkbook=WorkbookFactory.create(inputStream, password)
Cf here

Additionally I recommend to upgrade to POI 3.15 or better higher due to
security flaws found in previous versions.

You need to provide more source code so that we can help you...
Sometimes excel formulates formula results as General/Text and not number. This
would be one possible out of several explanations.

You can use the streaming / event API for low footprint reading

50 mb compressed can easily be several hundred MBs uncompressed. Especially
with Java Datentypes. You should increase the memory by at least 2 other GB, if
you want to stay with your current solution.
Depending on your workbook structure you could skip reading sheets which are
not relevant or j
Load them in parallel ... multiple cores alone will not help you have to create
threads of which each of them loads one or more files (depending on your use
case).
BTW your code does not load linked workbooks or evaluated formulas linked to
other workbooks.

I think only poi 4.0 officially supports JDK 8 only and not JDK7 anymore.
Poi 3.17 supports 6,7,8.
I am not sure if Poi is jdk 9 ready rested yet. Maybe the upcoming release 4.0
will be but the release manager can give you some definitive answer.
Do you need any specific jdk9 feature ?
> On 7.
The private key will not be in the Excel file - because it is private. You may
find the public key. However, if your original purpose is signature
verification then why not use the POI functions to verify it:

Dear all,
as part of the HadoopOffice library (
https://github.com/zuinnote/hadoopoffice/wiki) we provide the functionality
to read office documents, such as MS Excel, on Big Data platforms, such as
Hadoop/Hive/Spark/Flink.

Don't worry, I guess it was too late in the evening. I simply shade the
dependency to commons-compress and everything seems to work (and I still
can keep the POI integrated security mechanisms). Thanks btw. for 4.0.0

will need to shade the dependencies for their application, but I provide
examples, so it is not such a big issue to change.

Hi,
I get the following exception when I run my POI based application on a
certain platform (Apache Flink):

I should add that this used to work with Apache POI 3.17

What is your build file? It looks like libraries are mixed up.

You have to install the unrestricteds encryption policies, if you use Oracle
JDK:

Note you need the right version matching your JDK.

I think you can’t due to the Excel format. SXSSF creates temporary files and
does not need to keep everything in memory. I recommend though to activate
compression for those as they are heavy uncompressed

Can you share the code of the unit test?
Maybe the file is not properly closed on the application server or there is an
unlogged exception.
