| String Data |
| ----------- |
| Created by modifying Impala's HdfsAvroTableWriter(removed). |
| |
| These files' schemas have a single nullable string column 's'. |
| |
| negative_string_len.avro: contains two values, but the second value has a negative length. |
| |
| invalid_union.avro: contains three values, all of which have an invalid union value (4, |
| which decodes to 2). Also has a single extra byte at the end (0x0a), which will be |
| interpreted as a malformed data block. |
| |
| truncated_string.avro: contains one value, which is missing the last byte. |
| |
| Float Data |
| ---------- |
| Created by modifying Impala's HdfsAvroTableWriter(removed). |
| |
| These files' schemas have a single nullable float column 'c1'. |
| |
| truncated_float.avro: contains two float values. The second is missing the last byte. |
| |
| Bad Schema |
| ---------- |
| Created by editing the schema of a valid Avro file with vim. |
| |
| invalid_decimal_schema.avro: two columns, name STRING and value DECIMAL(5,7). |
| The DECIMAL value is invalid. |
| |
| Date Data |
| --------- |
| out_of_range_date.avro: |
| Small avro table with a single DATE column. Contains 5 values, two of which are out of |
| range. |
| |
| hive2_pre_gregorian_date.avro: |
| Small avro table with one DATE column, created by Hive 2.1.1. |
| Used to demonstrate avro interoperability issues between Hive and Impala for dates |
| before the introduction of Gregorian calendar in 1582-10-15. |
| |
| hive3_pre_gregorian_date.avro: |
| Small avro table with one DATE column, created by Hive 3.1.0. |
| Used to demonstrate that pre-Gregorian avro dates written by Hive3 are read back correctly |
| by Impala. |
