[jira] [Commented] (ARROW-13381) [C++][Flight] ArrayFromJSON
doesn't work for float value dictionary type
[ https://issues.apache.org/jira/browse/ARROW-13381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17383446#comment-17383446 ]
Eduardo Ponce commented on ARROW-13381:
---------------------------------------
The error occurs because there is no dict converter implemented for floating-point types in [*ipc/json_simple.cc*|https://github.com/apache/arrow/blob/master/cpp/src/arrow/ipc/json_simple.cc#L779-L798].
The code path is as follows: *Call to ArrayFromJSON(...)* -> [ArrayFromJSON(DataType, string_view)|https://github.com/apache/arrow/blob/master/cpp/src/arrow/testing/gtest_util.cc#L406] -> [ArrayFromJSON(DataType, string_view, Array)|https://github.com/apache/arrow/blob/master/cpp/src/arrow/ipc/json_simple.cc#L870] -> [GetConverter(DataType, Converter)|https://github.com/apache/arrow/blob/master/cpp/src/arrow/ipc/json_simple.cc#L808] -> [GetDictConverter|https://github.com/apache/arrow/blob/master/cpp/src/arrow/ipc/json_simple.cc#L763]
