Weâd like to introduce a new columnar storage format for Hadoop called Parquet, which started as a joint project between Twitter and Cloudera engineers.
There are two birthstones for the month of June. Alexandrite was the traditional birthstone for June, but due to its scarcity and cost, pearl has become June's common birthstone. The alexandrite was named after Czar Alexander II and is one of the most desired gems. Its color changes with the lighting surrounding the stone, which is called its phenomena.
The birthstone colors are red for January and July, purple for February and June, blue for March, September and December, white or clear for April and as an alternate for June, green for May and August; pink or multi-color for October and yellow for November.
