The code that backs the `bin/accumulo rfile-info hdfs://path/to/rfile.rf` command is located at https://github.com/apache/accumulo/blob/3fd5cad92f9b63ac19e4466f3f2d5237b905262c/core/src/main/java/org/apache/accumulo/core/file/rfile/PrintInfo.java
It may be a useful example of how to read key/value pairs from an RFile to implement such a thing. However, that code uses a lot of internal APIs. We have a public API (since 1.8) for reading from RFiles that is probably better to use: https://accumulo.apache.org/docs/2.x/apidocs/org/apache/accumulo/core/client/rfile/RFile.html#newScanner() On Fri, Jan 10, 2020 at 5:21 PM Bulldog20630405 <bulldog20630...@gmail.com> wrote: > > > accumulo has an AccumuloFileOutputFormat which i use all the time; however, > there is not an AccumuloFileInputFormat. does anyone have an example? or at > least how an rfile structure is so i can parse it one key at a time? > >
