hi all, 最近在1.11上使用io.extra-file加载外部http文件出现一点小问题
由于http的文件在FileSystem.getFileStatus去拿状态时会走HttpFileSystem的类的getFileStatus方法,该方法返回的FileStatus中length为-1。 在client端校验通过后,在decodeYarnLocalResourceDescriptor的时候会碰到问题。 异常如下: 2020-12-04 17:01:28.955 ERROR org.apache.flink.yarn.YarnResourceManager - Could not start TaskManager in container containerXXXXXX. org.apache.flink.util.FlinkException: Error to parse YarnLocalResourceDescriptor from YarnLocalResourceDescriptor{key=XXXXX.jar, path=https://XXXXXXX.jar, size=-1, modificationTime=0, visibility=APPLICATION} at org.apache.flink.yarn.YarnLocalResourceDescriptor.fromString(YarnLocalResourceDescriptor.java:99) at org.apache.flink.yarn.Utils.decodeYarnLocalResourceDescriptorListFromString(Utils.java:721) at org.apache.flink.yarn.Utils.createTaskExecutorContext(Utils.java:626) at org.apache.flink.yarn.YarnResourceManager.getOrCreateContainerLaunchContext(YarnResourceManager.java:746) at org.apache.flink.yarn.YarnResourceManager.createTaskExecutorLaunchContext(YarnResourceManager.java:726) at org.apache.flink.yarn.YarnResourceManager.startTaskExecutorInContainer(YarnResourceManager.java:500) at org.apache.flink.yarn.YarnResourceManager.onContainersOfResourceAllocated(YarnResourceManager.java:455) at org.apache.flink.yarn.YarnResourceManager.lambda$onContainersAllocated$1(YarnResourceManager.java:415) 。。。。。 因为正则匹配的size只能匹配数字 private static final Pattern LOCAL_RESOURCE_DESC_FORMAT = Pattern.compile("YarnLocalResourceDescriptor\\{" + "key=(\\S+), path=(\\S+), size=([\\d]+), modificationTime=([\\d]+), visibility=(\\S+), type=(\\S+)}"); 负号不能被匹配上,想要实现加载http的文件需要mock一个length大于-1的FileStatus。 想问下各位大佬,看到有加载remote文件的功能,这块功能是不是给远程hdfs上文件用的,并没有考虑到http文件呢? |
Hi,
你指的是 `yarn.provided.lib.dirs` 吗? 这个地方设计的时候确实是只考虑到了 hdfs,没有考虑 http 文件。 我刚刚也和熟悉 hadoop 的朋友确认了一下,从 yarn 的层面上应该也是支持 http 文件的,所以 flink 最好也是能支持 http 文件。 由于整个 feature 在设计的时候都没有考虑到 http 文件的问题,不确定修复了正则匹配的问题后是否还会有其他问题。 我开了 FLINK-20505 来跟踪 provided lib 支持 http 文件的整体进度。 https://issues.apache.org/jira/browse/FLINK-20505 Thank you~ Xintong Song On Mon, Dec 7, 2020 at 10:03 AM zhou chao <[hidden email]> wrote: > hi all, 最近在1.11上使用io.extra-file加载外部http文件出现一点小问题 > > 由于http的文件在FileSystem.getFileStatus去拿状态时会走HttpFileSystem的类的getFileStatus方法,该方法返回的FileStatus中length为-1。 > 在client端校验通过后,在decodeYarnLocalResourceDescriptor的时候会碰到问题。 > 异常如下: > 2020-12-04 17:01:28.955 ERROR org.apache.flink.yarn.YarnResourceManager - > Could not start TaskManager in container containerXXXXXX. > org.apache.flink.util.FlinkException: Error to parse > YarnLocalResourceDescriptor from YarnLocalResourceDescriptor{key=XXXXX.jar, > path=https://XXXXXXX.jar, size=-1, modificationTime=0, > visibility=APPLICATION} > at > org.apache.flink.yarn.YarnLocalResourceDescriptor.fromString(YarnLocalResourceDescriptor.java:99) > at > org.apache.flink.yarn.Utils.decodeYarnLocalResourceDescriptorListFromString(Utils.java:721) > at > org.apache.flink.yarn.Utils.createTaskExecutorContext(Utils.java:626) > at > org.apache.flink.yarn.YarnResourceManager.getOrCreateContainerLaunchContext(YarnResourceManager.java:746) > at > org.apache.flink.yarn.YarnResourceManager.createTaskExecutorLaunchContext(YarnResourceManager.java:726) > at > org.apache.flink.yarn.YarnResourceManager.startTaskExecutorInContainer(YarnResourceManager.java:500) > at > org.apache.flink.yarn.YarnResourceManager.onContainersOfResourceAllocated(YarnResourceManager.java:455) > at > org.apache.flink.yarn.YarnResourceManager.lambda$onContainersAllocated$1(YarnResourceManager.java:415) > 。。。。。 > 因为正则匹配的size只能匹配数字 > > private static final Pattern LOCAL_RESOURCE_DESC_FORMAT = > Pattern.compile("YarnLocalResourceDescriptor\\{" + > "key=(\\S+), path=(\\S+), size=([\\d]+), modificationTime=([\\d]+), > visibility=(\\S+), type=(\\S+)}"); > > 负号不能被匹配上,想要实现加载http的文件需要mock一个length大于-1的FileStatus。 > 想问下各位大佬,看到有加载remote文件的功能,这块功能是不是给远程hdfs上文件用的,并没有考虑到http文件呢? > |
