### Describe the bug, including details regarding any error messages, version, and platform. In the following schema file, it is assumed that there is a single type for all `indptr` buffers and another single type for all `indices` buffers. However, in the C++ implementation, each `indptr` and `indices` buffer can have its own type. **Schema files** [https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/format/SparseTensor.fbs#L160](https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/format/SparseTensor.fbs#L160) [https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/format/SparseTensor.fbs#L179](https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/format/SparseTensor.fbs#L179) **C++ implementation** Note that each tensor is associated with its own type: [https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/cpp/src/arrow/sparse\_tensor.h#L445-L447](https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/cpp/src/arrow/sparse_tensor.h#L445-L447) In the C++ IPC implementation, however, the type of the first `indices` and `indptr` buffer is generalized to all: [https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/cpp/src/arrow/ipc/metadata\_internal.cc#L1152-L1153](https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/cpp/src/arrow/ipc/metadata_internal.cc#L1152-L1153) [https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/cpp/src/arrow/ipc/metadata\_internal.cc#L1158-L1159](https://github.com/apache/arrow/blob/d803afcc43f5d132506318fd9e162d33b2c3d4cd/cpp/src/arrow/ipc/metadata_internal.cc#L1158-L1159) ### Component(s) C++, Documentation, Other -- This is an automated message from the Apache Git Service.
