wangxiyuan commented on FLINK-13449: ------------------------------------ Take [testBlockingPartitionIsConsumableMultipleTimesIfNotReleasedOnConsumption|https://github.com/apache/flink/blob/master/flink-runtime/src/test/java/org/apache/flink/runtime/io/network/partition/ResultPartitionTest.java#L122] as an exmaple: Since aarch64 is not supported, the [BoundedBlockingType|https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/io/network/partition/ResultPartitionFactory.java#L197] will be *FILE* instead of *FILE_MMAP*. Then when read the [Buffer|https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/io/network/partition/BoundedBlockingSubpartitionReader.java#L71], it try to [get 4 bit|https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/io/network/partition/BufferReaderWriterUtil.java#L159], but the segment is only 1 bit, then *IndexOutOfBoundsException* error raised. Just explained from code layer, since I'm still a newbie for Flink, Sorry that I don't know the deep Flink concept at this moment. > Add ARM architecture to MemoryArchitecture > ------------------------------------------ > > Key: FLINK-13449 > URL: https://issues.apache.org/jira/browse/FLINK-13449 > Project: Flink > Issue Type: Sub-task > Reporter: Stephan Ewen > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > Currently, {{Memoryarchitecture}} recognizes only various versions of x86 and > amd64 / ia64. > We should add aarch64 for ARM to the known architectures. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
