Greetings, We have a Java application, and we were using the old 2.6.1 HDF Java libraries for our day-to-day activity. But recently due to some changing requirements, we have to change it to 3.3.2. We have an ETL process which consists of number of scripts that perform read/write functions (mostly read) to HDF5 files. ETL is running on Linux environment (tens of nodes) and it is working completely fine with 2.6.1 version. But, with 3.3.2 version, it’s throwing out several errors when trying to read HDF5 files. However, the odd thing is that it DOES read the attributes but dumps out errors related to C libraries. Here are some of the log errors: ` INFO | jvm 1 || getting the location:/SETTINGS/CHANNEL_01/LOCATION INFO | jvm 1 || HDF5-DIAG: Error detected in HDF5 (1.8.19) thread 0: INFO | jvm 1 || #000: /scr/home/buildbot/buildbot/kituo-slave/hdf518-StdRelease-code-centos7/build/hdfsrc/src/H5A.c line 474 in H5Aopen_by_name(): can’t open attribute INFO | jvm 1 || major: Attribute INFO | jvm 1 || minor: Can’t open object` INFO | jvm 1 || #001: /scr/home/buildbot/buildbot/kituo-slave/hdf518-StdRelease-code-centos7/build/hdfsrc/src/H5Aint.c li ne 454 in H5A\_open\_by\_name(): unable to load attribute info from object header INFO | jvm 1 || major: Attribute INFO | jvm 1 || minor: Unable to initialize object INFO | jvm 1 || #002: /scr/home/buildbot/buildbot/kituo-slave/hdf518-StdRelease-code-centos7/build/hdfsrc/src/H5Oattribut e.c line 535 in H5O\_attr\_open\_by\_name(): can’t locate attribute: ‘PALETTE’ INFO | jvm 1 || major: Attribute INFO | jvm 1 || minor: Object not found INFO | jvm 1 || getPaletteRefs(): Palette attribute search failed: Expected INFO | jvm 1 || hdf.hdf5lib.exceptions.HDF5AttributeException: Object not found INFO | jvm 1 || at hdf.hdf5lib.H5.\_H5Aopen\_by\_name(Native Method) INFO | jvm 1 || at hdf.hdf5lib.H5.H5Aopen\_by\_name(H5.java:1064) INFO | jvm 1 || at hdf.object.h5.H5ScalarDS.getPaletteRefs(Unknown Source) INFO | jvm 1 || at hdf.object.h5.H5ScalarDS.init(Unknown Source) INFO | jvm 1 | | init(): H5Tget\_class: 3 is Array 10 INFO | jvm 1 | | HDF5-DIAG: Error detected in HDF5 (1.8.19) thread 0: INFO | jvm 1 | | #000: /scr/home/buildbot/buildbot/kituo-slave/hdf518-StdRelease-code-centos7/build/hdfsrc/src/H5F.c line 701 in H5Fflush(): not a file or file object INFO | jvm 1 | | major: Invalid arguments to routine INFO | jvm 1 | | minor: Inappropriate type INFO | jvm 1 | | close(): H5Fflush(did 1186443) failure: INFO | jvm 1 | | hdf.hdf5lib.exceptions.HDF5FunctionArgumentException: Inappropriate type INFO | jvm 1 | | at hdf.hdf5lib.H5.H5Fflush(Native Method) Any help on this matter would be greatly appreciated. ---

3.3 hdfjava added exception handling and reporting. This is likely what you are running into, they were always there, just being ignored. Also, hdfjava would always check for image attributes by name, if a dataset was opened and those log errors are a result of blindly calling H5Aget\_attribute\_by\_name. Allen
